Have you researched using better bidding dot com? Have you read all of the fine print including if there is a resort fee (on the "Know Before You Go?" section all the way to the bottom) What filters did you use? Airport shuttle in the Bonnet Creek area is pretty much a dead giveaway that it is a Disney resort, but using Hotwire is a gamble and you have to be ok with all of your potential options before you book. Just remember, though, that the Hilton Bonnet Creek resort area (I think there are a few hotels within there too) is one of the popular options that is in the Disney Bonnet Creek area filter of Hotwire. Most of their hotels charge the resort fee, so be sure to know those options as well.
That being said, I have used Hotwire on many non-Orlando vacations and have always gotten between one or two of what I narrowed down based on my research and have been very happy with my rooms. I am really glad that Disney rooms became part of Hotwire and might utilize it when I travel next. I am a little worried about getting CBR or CSR with the construction so I might stick to a value on this trip.
Good Luck!
