I Need Some Ideas For My Party...

I am having a party with probably 4 of my best friends in the middle of january and we are gonna go to a hotel and spend the night there and i was wondering what ideas you may have for doing there....i live in texas, so its not extremely cold (well, duh) outside, but its not really warm either, the hotel we are staying has an indoor pool and all, but i was wondering what else we could do while we`re there....if you have any ideas, any at all ( :-) ), please tell me....thanks
*mwah, i luv ya (ok, yea, not really, but, sure, whatever)*
