Hotel room prices change quicker than a Lady Gaga look. Such malleability works for the Lady but isn't so great for travelers. If you already use Expedia to book hotel rooms, then you've every reason in the world to mosey on over to their new-ish sister site (with a sassy name) Tingo, to combat this pesky problem. On it, you can use Expedia's resources to book hotels, but Tingo monitors the price of the room you've reserved and automatically rebooks and gets you a refund if (and when) the price of the room goes down. Like, say you're going to Spain for party season this summer (go before it all falls apart...)...we'll say Madrid (so the new Barcelona by the way, even if there's no beach).

If you book at the Room Mate Oscar (which you should do if you want to really party it up Madrid style), Tingo will watch the rates for you and make sure you're paying the lowest cost possible. Most online booking sites already offer you a guarantee, but its up to you to monitor and do all the calling and emailing to get your refund. Tingo.com began earlier this year and continues to delight users with more money to spend in your hotel's bar or restaurant. Word.
