While I haven't seen the ad, I am guessing it probably says something like "starting at $27". If this is the case, the time of year you are going is probably dictating the price. Just like Disney has different pricing seasons, all the hotels in the Orlando Area I have read about seem to follow the same deal. In the slower seasons they charge less, in the peak seasons they charge more.
And truthfully, $32 a night is a very good price even if you can't get $27.
You might want to post this on the Orlando Hotels and Attractions Board as that is the board where people will have more experience with off Disney property hotels will be reading.
