PROBLEM: (CNN) -- Poaching tourists from the trendy tango bars of Buenos Aires or the glamorous beaches of Rio de Janeiro would be a tall task for most cities. But the Chilean capital, Santiago, is looking to do just that by encouraging travelers passing through on business to stay and uncover its potential as a hip South American destination. Chile has become one of the continent's leading locations in which to do business in recent years. Foreign investment increased by 80 percent in 2011 alone, totaling $12 billion for the year according to Daniel Pardo, director of SERNATUR, the Chilean tourism ministry. As a result, the number of foreigners coming into the country for trade purposes has increased along a similarly sharp upward curve. This surge has been concentrated mainly in Santiago, Chile's nerve center and economic engine room, and it's here that Pardo and the country's tourist board spy an as yet untapped opportunity. "Hopefully by bringing out those business people that are coming here for a week to do their jobs (they will) stay for the weekend and enjoy the country," Pardo told CNN's Richard Quest. "There's a lot of interest in coming to Chile," he adds. "And we've seen it in our numbers, with a 60 percent growth in tourism this year." See also: Exploring the mystery and beauty of Chile . Travelers who take up the invitation to hang around will find a variety of parks, churches and museums which offer a wealth of easily accessible tourist sites -- ideal for the culture vulture with a couple of hours to spare. For those with a little more time on their hands meanwhile there is even more to explore and experience around the city's outskirts and beyond. With the Santiago business traveler in mind, CNN asked Lonely Planet's Bridget Gleeson, co- author of Lonely Planet Chile and Easter Island Travel Guide, to lend her expertise in selecting the city's best spots. In the city . Santiago offers an intriguing mix of both the modern and the classic. Historic sites such as the Catedral Metropolitana contrast sharply against the rowdy Mercado Central fish market, which offers "a colorful attraction for photographers and foodies alike," says Gleeson. Touring the city's downtown district on foot is a particularly nice way to explore Santiago, she adds, while the nearby Centro Cultural Palacio La Moneda museum plays host to the finest Chilean modern art. Other Santiago highlights include Museo de la Moda (Museum of Fashion) in the Vitacura district -- which includes famed items such as John Lennon's jacket and the famous "cone bra" Jean Paul Gaultier designed for Madonna -- and the 300 meter high San Cristobal lookout point. Valparaiso . The picturesque seaside resort of Valparaiso is a UNESCO world heritage site and a heaving modern port that is integral to Chile's vast export industry. See also: Singapore on a stopover . A little under two hours from Santiago by road, the town is perched atop a dozen or so hills which offer spectacular vistas out across the Pacific Ocean. Vistors can "tour (the Chilean poet and author) Pablo Neruda's charming hilltop house, La Sebastiana" or "board one of Valparaiso's 15 antique ascensores (elevator cable cars) ... to take in vibrant street art and stunning views over the ocean," says Gleeson. Those on a quick stop-off before heading back to Santiago however may make the most of their time by taking "a quick boat ride from Muelle Prat (harbor) to get a feel for the city," Gleeson advises. Observatories . With an average of more than 330 cloudless nights per year, Chile is a near perfect natural laboratory for astronomers and stargazers. It is for this reason the country will host 68 percent of global astronomy infrastructure by 2018, according to the national government. But you don't have to be an acolyte of Alfred Hubble to enjoy the sparkling contents of the Chilean night sky. The Paielan Observatory in the Maipo Valley is just 50 kilometers from Santiago and is surrounded by a spectacular, unspoilt nature reserve. A world class restaurant on the premises meanwhile serves up the latest in contemporary Chilean cuisine, enabling visitors to enjoy fine dining under the stars. Wine regions . Chile is a major exporter of wine and visiting some of its fertile vineyards is a rite of passage for many a connoisseur. See also: Making the most of wine at 35,000 feet . Almost 17 million people drink a glass of Chilean wine every day and the country is the world's largest grape exporter. "Many travelers opt to visit a few wineries with a specialist like Uncorked Wine Tours," says Gleeson. These customized tours include an English-speaking guide, visits to three wineries and a leisurely lunch in wine country. Those looking to go it alone on a wine-tasting odyssey meanwhile can reach some of the lesser visited wineries in the Santiago region by public bus in little over an hour. If you're planning an independent visit, Gleeson warns however, it is wise to log onto the wineries' websites to find out about specialty tastings, picnics, and additional activities before setting out.

PROBLEM: As they make a final push to approve presidential nominations before Republicans take control of the Senate, Democrats said Tuesday the confirmation of a record number of federal judges was evidence they were right to make controversial changes to filibuster rules, despite objections from Republicans. "Yes," Senate Majority Leader Harry Reid responded loudly when asked if still believes he was right to employ the so-called "nuclear option" a year ago in order to clear a backlog of nominees. The No. 2 Senate Democrat explained that at the time there was a "breakdown in the relationship between the executive and legislative branch." "If you just look at where we were, with all of the nominations stacked on the calendar, most of which had been reported from committees with overwhelming bipartisan votes," Sen. Dick Durbin said.  "Republicans were trying to keep as many nominations from final approval as possible. So we had no choice." During the first year of the congressional session, before the nuclear option, the Senate confirmed a total of 36 federal district and circuit court judges appointed by the President.  After the rules changes, which took place Nov. 21, 2013, the number of judges confirmed more than doubled to 84. The rules change lowered the number of votes needed to overcome a filibuster from 60 to 51, making it much easier for Democrats, who currently have a 54 to 46 majority, to approve judges to those lifetime positions. Before the Senate adjourns, probably in the next day or two, Democrats hope to confirm an additional 12 district court positions. Democrats this week also cleared a new surgeon general, a top immigration official, and were ready to approve Tuesday the No. 2 at the State Department. Each of those people faced serious GOP opposition and might not have been cleared if not for the rules change. "The train is running over everyone. That's the Reid train. Last trip around the track," complained Sen. John McCain, R-Arizona about the last minute wave of judicial and executive branch nominations Senate Democratic Leader Reid is jamming through. "It's a result of the nuclear option which deprived us of our ability to advise and consent and it's shameful. McCain and other Republicans also blamed Sen. Ted Cruz, R-Texas, and a small group of other conservatives who forced a weekend session that Reid used to clear procedural hurdles on a number of nominees. "It was also caused in part by what happened last weekend when several nominees who are controversial are now going to receive Senate votes and are probably going to be confirmed who otherwise probably would not have been," said Sen. Susan Collins, R-Maine.

SOLUTION: Democrats say they have no regrets over changing the Senate rules to approve more judges .
Republicans, who will take control of the Senate in January, are upset with the maneuver .

PROBLEM: Islamabad, Pakistan (CNN) -- A suspected U.S. drone attack killed five people early Wednesday in Pakistan's tribal region that borders Afghanistan, two Pakistani intelligence officials said. It was the first drone strike since demonstrators marched to the border of Pakistan's tribal region over the weekend to protest the attacks. Activists from the United States and Britain participated in the march, which was led by the cricket star turned politician Imran Khan. Opinion: Why U.S. will live to regret drone strikes . Opinion: Could spread of drones mark new arms race? Four missiles were fired Wednesday at a suspected militant hideout in the area of Mir Ali of North Waziristan, one of the seven districts of the volatile tribal region, the two intelligence officials said, requesting anonymity because they were not authorized to speak about the matter to the news media. The protest march against U.S. drone strikes in Pakistan came to a halt on Sunday when authorities used steel shipping containers and security forces to block access to the demonstration's final destination in the tribal region. When confronted with the roadblock, Khan directed protesters to turn back, saying the march had achieved its goal of drawing attention to the controversial U.S. drone strikes.

Khan has been a fierce critic of U.S. policy in Pakistan and the use of drone strikes, calling them a violation of Pakistan's sovereignty and a strategy that stokes militant anger towards Washington. In recent years, the U.S. government has sharply stepped up the use of drone attacks in Pakistan's mostly ungoverned tribal region, widely believed to be a safe haven for militant groups fueling the insurgency in Afghanistan. U.S. officials say the drone strikes are an effective strategy against militant groups and insist civilian casualties are rare. Read more: U.S. study says drones kill, traumatize too many civilians .
