I travel ALOT for work, but luckily for me i dont have to pay for any of it hahaha. But when my family does or i take the occasional vacation... from vacationing... i flood the review forums to save me bucks. I am especially cheap since im used to not paying for stuff, so when i actually pay to stay at a hotel, i make sure im getting the cheapest possible deal. Upon my searches, i found this lovely site with a list and explanation of great sites to save you loads of money and educate you with reviews and advice on how not to get ripped off. Enjoy!
