The price I found was on alpharooms, for 2 people in a room. Last year though, we got 2 rooms for Oasis, one was fine, the other they claimed we shouldve been told was overbooked and was moved to the other oasis (nice one) down the way. We still didn't want it and were pissed. Our friends with that room finally ended up just paying the 25/day extra to upgrade to the Grand for the week. Not sure if that had something to do with alpharooms or Oasis, but that was annoying.
If you book from them again, I'd recommend calling/emailing the hotel a couple days after booking to reconfirm your reservation. Do it again a week before your trip. If you bug the hotel enough about making sure your room will be there for you, your room will probably be there for you.
