Limit the amount of cash and bank cards you carry with you, so if something does happen, you can easily recover. Never take more than one credit card or ATM card with you. My rule for cash is to limit what I carry to $50 USD.
Always carry a lock – They come in handy, especially when you stay in dorms and need to lock your stuff up. Carry a small combination lock with you when you travel. Don’t use one with keys because, if you lose the keys, you’re screwed!
Make extra copies of your passport and important documents – Don’t forget to e-mail a copy to yourself too. You never know when you might need to have some sort of documentation with you and might not want to carry your original. Additionally, if your passport gets stolen having a copy will come in handy for your police report.
Hostel staff deal with budget travelers all day, every day. They know exactly where to go for cheap meals and attractions. They also tend to be locals so they know the city very well. Ask them for all sorts of information. Even if you aren’t staying in one, just pop in and ask for help. They’ll usually give it.
Learn basic phrases in the native language of your destination – The locals will appreciate it and it will make your interactions easier. You don’t need to master the language but learning a few things like “Hello,” “Goodbye,” “Thank you!”, “Where’s the bathroom?” will go a long way to endearing yourself with the locals. They’ll like that you tried.
Read a history book! – You can’t understand a place’s present if you don’t know anything about its past. Read up on the destinations you are visiting. It will give you a deeper understanding of this place you’ve wanted to see for so long!
Don’t be ashamed to walk into a Starbucks or McDonald’s – Sometimes familiarity is comforting and both places have free wifi and public restrooms you can use. (Just don’t eat the food at McDonald’s! That shit is gross and unhealthy for you! You can get it back home!)
