Every trip I have ever taken, I used a Lonely Planet guidebook, and I swear by them! They may not be the cheapest travel guides, but they certainly can save you money with their extremely detailed and helpful budgeting tips. All their guides are available in pdf formats, hard copies, and even on kindle!
Their policies are designed for adventurous travellers with coverage for overseas medical, evacuation, baggage and a range of adventure sports and activities. You can buy and make claims online, even after you’ve left for your trip. I have been using them for every trip I take for the last few years and luckily only needed to cash in once in Thailand. I had to go to the hospital for a scuba diving injury and World Nomads completely reimbursed me for my $115 medical bill. Even if you don’t think you’ll need it, think again. After seeing a friend first hand get helicoptered out of Uganda, racking up a $300,000 bill (all covered by insurance) I realized that it’s always better to be safe than sorry.
