I've seen a few 802.11b mods online that will allow you to build a transmitter that can broadcast 1-2 miles using a pringles can and some cabling. It's very uni-directional though, so you'd probably have to put a reciever somewhere and rebroadcast the signal into the hotel. Cost of pringles can: $3.50. Cost of cabling, $10. If you can be so precise as to aim it at your hotel window, I'd guess you'd be in good shape
