INPUT ARTICLE: Article: Keep in mind that the cheaper your ticket is, the more add-on charges will be available on the ship, and the more expensive the ticket is up front, the more all-inclusive it is. Give yourself a set amount of money for spending so you can better plan which activities and options to participate in. Cruises can usually be booked up to 18 months in advance, guaranteeing your first choice of cruise and cabin location. Booking ahead of time will give you more options and availability, particularly if you're traveling with a large group. Some cruise lines offer incentives to book early, such as prepaid gratuities or a free dinner in a specialty restaurant, so planning ahead could save you some money. Generally, you can book a cruise as little as a week before embarking. Booking short notice gives you fewer options, but a better chance to get a good deal. Cruise lines also sometimes offer special short-notice deals and incentives for cruises that haven't filled completely. You'll find a variety of good deals and special offers during "Wave Season," the name the cruise industry gives the time from January to March when most people buy their tickets. You can often find good deals when booking directly through the cruise line. Travel agents often offer special perks and discounts like on-ship credit and prepaid gratuities. If you have time to research and compare prices and you know what you want, buying online directly through the cruise line can be a great way to find the best deals. However, experienced travel agents can also help you find the cruise line that best fits your preferences as well as the best rooms on the ship. If you do choose to go with an agent, make sure they know what you want and your budget. Ask lots of questions and don't let them push you into anything you aren't completely happy with. Not all cabins are the same, so depending on your experience and budget, make sure to pick one that fits your needs. If this is your first cruise, choose a midship cabin located on a lower deck. If you find out that you do tend to get seasick, this will be the best place for you as it experiences the least amount of movement. If you're on a tighter budget, look into windowless rooms and "guarantees," which may let you upgrade to a better room for free if one is available. If you have a bit more freedom with your budget, consider booking a balcony room with amazing views of the scenery as you cruise by. If it's your first cruise or the area is particularly hard to navigate, signing up for the cruise line-guided shore excursions is a great option. These excursions range from snorkeling and hiking to shopping at outdoor markets and wine-tasting. Consider what kind of excursion you're drawn to--active or sightseeing activities, full or half-day tours, guided or free time, and highlights or in-depth. While casual restaurants are mostly first come, first served, you should make reservations for any sit-down restaurants. Although many accept walk-ins, it is recommended that you book your visits ahead of time to guarantee your spot, particularly for the more popular restaurants.

SUMMARY: Set a budget. Book your ticket in advance for guaranteed availability. Book your ticket last-minute to catch a price break. Find a good deal. Book online or with an agent. Choose the best cabin to suit your needs. Book online excursions to match your interests. Find dining options ahead of time.

INPUT ARTICLE: Article: Doing so helps keep your bones strong, which may help reduce your chances of a stress fracture in the future. For women under 50 and men under 70, you need 1,000 milligrams of calcium a day; after that, you need 1,200 milligrams. Dairy products are a good source of calcium, particularly ones fortified with vitamin D, which aids your calcium absorption. Fortified orange juice, fortified tofu, canned salmon (with the bones), kale and other greens, and sardines are all good sources of calcium. Vitamin D is mainly found in fatty fish, such as mackerel, tuna, and salmon, as well as fortified foods like cereal, juices, and milk. You can also get vitamin D from sunlight on your skin, but going outside without sunscreen can put you at risk for sun cancers. Supplements are also an option, but always talk to your doctor first. If you're under 50, you need 400-800 IUs per day or 800-1,000 if you're over 50. Running on inconsistent surfaces like sand or even grass can set you up for an injury. Sloping, holes, and surfaces that change from hard to soft make your body work harder and can lead to injuries like stress fractures. Opt for a running track when you can. Running shoes absorb some of the shock of your feet hitting the ground, which helps relieve the pressure that could cause stress fractures. Make sure your shoes fit well and are made specifically for running. Go to a store to be fitted the first time you buy shoes; after that, you can purchase them online if you prefer. Make sure to change your shoes out every 250 to 500 miles (400 to 800km) of use. If you notice your shoes have lost much of their "bounce," it's time to change them out. If you always run for your exercise, you get repeated impacts on the same part of your legs. Instead, choose lower-impact activities for part of your exercise, which will help take the pressure off. For instance, try swimming or bicycling. Strength training helps build up your muscles, which in turn provide support for your bones. With stronger muscles, you're less likely to get a stress fracture. Strength training involves using your body weight, resistance bands, or free weights to slowly build up your muscles through resistance. Pushups, situps, squats, lunges, and chest presses are all examples of strength training.

SUMMARY:
Ensure you're getting enough vitamin D and calcium in your diet. Run on a smooth, somewhat soft surface like a track. Purchase good running shoes. Include cross-training in your routine. Make strength training a part of your workout.
