Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Input: Consider Input: I am planning a trip to northern Italy. I will start it with two days of Giro d'Italia in and around Genoa and then I will move on to Verona for a javascript conference. I was thinking that flying to Milan (from Sweden) would be the best option and then get around by train. However I just now realized that although Genoa is an hour or so from Milan by train - Verona is more like 4 hours and a stop in Bologna.

Are there any obvious better way to do this than flying to Milan?

UPDATE: I had it wrong about train from Verona to Milan - it is also 1-2 hours. Still it is a bit cumbersome to travel like this.

Output: Airport options for trip to Genoa and Verona

Input: Consider Input: In a while I will be traveling to Norway for a hiking trip. In between getting from the Oslo Gardermoen airport to Finse, I'll have to get gas cans with a that are UNEF 7/16" threaded, which means they look like this:

Any tips on where to get these? preferably at shops near the airport.

I already found Oslo sportslager, who sell these for sure: http://www.oslosportslager.no/produkt/beaver-power-gas-450-gassboks-25070.aspx

But in case they're out of it, it would be nice to have a backup plan :)

Input: Consider Input: (In a similar vein to this question on hotel room upgrades and this question on flight upgrades...)

Most regular car rentals agencies have various categories of car - Budget/Economy, Compact, Midsize, Fullsize, etc. The names vary from agency to agency and around the world, but the principles are similar.

Generally the "better" the category, the better the car - larger, more luxury, etc.

What tips or tricks can you apply to get a better car or better benefits than you originally booked? This might result in a "better" car, or perhaps something else such as a free satnav included, free miles included, or some other perk that improves the overall value for money equation.

Some of the tips I've noticed are:

Being a regular renter with that agency, e.g. status with Hertz Gold Plus Rewards.
Turning up to a smaller (often in-town) rental location when they only have a few cars left, which can bag you a free upgrade (although this can also backfire and you can get a dismal car!).
