Due to an unusually busy schedule, I put this on the back burner for a while. I decided to split my bid and got a 4* (the Sheraton) for $95 for May 11-13. I'm still not sure what I'm going to do for May 9-11. I'm thinking of booking a room that I can cancel and trying a lower bid in a week or so. I've learned a lot (free rebids, split-bidding, etc) from this site. Thanks!
