Favourite websites?

Ok, so here in Budapest we're about to build a new website for the hostel and I have a few ideas - just looking for a little more inspiration. Does anyone have any favourite websites (as in, favourite designs or features rather then purposes) that theyve used as inspiration? Any cool features you've seen on websites - hostel/hotel or otherwise - that they've wanted to (or have) include(d)?

How about any hostel or hotel websites that have really grabbed your attention? Nothing revolutionary needed, just... well... cool.

Cheers
