So after being so unsure about where to stay offsite for our week after Disney, I finally booked the Radisson Lake Buena Vista. I booked it for $98.10/night with their prepaid hot deals rate. I look at the rate today, and it has gone down to $80.10 for 5 of my 7 nights. I call Radisson and they say it can't be changed because I booked it prepaid. Understandable, that is why that rate is lower. I ended up cancelling the reservation, and paying $25 to do so, but I still saved about $75!
It's just frustrating that the rate always seems to go down the day after I book, same thing happened with my flights!
