As much as I love to travel, I still have a budget. These websites are amazing for travelers on a budget:
1) http://www.Kayak.com – The cheapest flights I have ever found for International/Domestic travel
2) http://www.Ryanair.com – For European traveling, sometimes as cheap as 1 euro!
3) http://www.Hostelworld.com – For hostels…obviously
4) http://www.Tripadvisor.com – I never book a hostel or hotel without reading the reviews!
5) http://www.Kayak.com/explore – An interesting section of Kayak where you can type in your departure airport and then see a visual display of the cheapest airfares around the world.
