So whether you are in dire need of help or just want to have a friendly chat, don’t shy away from striking up a conversation with a total stranger; that is the best way to get a sense of Icelandic culture and society, and since all Icelandic students must learn English before they are allowed to graduate from elementary school, a language barrier will rarely, if ever, be an issue.
Most importantly, luggage should err on the safe side of the standard carry-on size -- in inches that means slightly under 22 x 14 x 9 (height x length x width), or 56 x 36 x 23 in centimeters, which is the most common allowable size across airlines. Many bags claim to be regulation size carry-ons and in fact aren't, so double check dimensions before buying to avoid forced gate check.
Checking out is when you’re most likely to lose something. Whenever I check out of a place, I check the bathroom, I check under the beds, I check the desks, and then I make sure I have my passport, laptop, camera, money, phone, and external hard drive. I’ll be fine if I leave anything else behind. Having a routine that you go through every single time will help you keep track of everything. I learned my lesson with this one when I left my passport behind in a guesthouse in Bagan, then left it in an apartment in London two months later.
This is a no-brainer, but it's something that many travelers don't think to do. If you missed the cancellation window for your hotel, restaurant, or car booking but can still change the reservation date free of charge, move your reservation back by several weeks or months. Then call back to cancel with a different representative. Sneaky? Sure. But it works, and you'll never get stuck with a lousy cancellation fee again.
“You can ‘de-materialize’ certain objects by replacing them with apps on you phone. The obvious example is the camera, but also think of the travel guide book, maps, the moleskine, books, magazines, etc. Also, if you are taking a long term trip, you can buy clothing from locals as you go with apps like Modabound (an Airbnb for clothing) and others.”
4. Record room numbers. If you’ve been on the road for weeks on end, it can be very hard to remember if you’re staying in room 304 -- or if that was last week’s hotel. When I park in a numbered spot or check into a new room, I create an entry in the “notes” function of my smartphone, so I can quickly remember where I’m going. It may sound unnecessary, but it’s saved a lot of confusion and grief.
It also helps to know which items are, according to the TSA, considered liquids or gels and thereby subject to the 3-1-1 rule. This isn't as simple as it sounds. Foods such as peanut butter, pudding, mashed potatoes, and icing are classified as gels. Mascara, lip gloss, and aerosol items are also classified as liquids or gels. But keep in mind that liquid prescription medication is exempt. (Read more on that on The TSA Blog.) See a more complete list of liquids and gels that are not permitted in carry-on luggage in quantities greater than 3.4 ounces here.
