@Jared and @Erik
Actually looking at it closer myself the Baiyoke Sky hotel does seem reasonable if you have 3 people splitting a room. I would probably only stay there Thursday night through Sunday night. At those prices I think it would be much more convenient to stay at the competition hotel, plus it would be kind of cool to stay in the Deluxe Sky zone

Staying in the Deluxe Sky Zone, and splitting a room between 3 people, seems to be running between about $40-$50 USD per night depending on how many nights which really is not bad at all!
--edit--
Actually, looking at it again even the Deluxe Space Zone (which would be really cool!) with Breakfast combo seems to be only around $50 USD per night if 3 people are splitting a room, and depending on length of stay a little bit too. Hmmmm..... This is looking more and more enticing.
