Summer Bay has a horrible reputation for saying one thing and giving you paper that says something else to sign.
I was contacted by them many years ago to buy a 'preview package' - and was told over the phone that I had 24 hours to cancel the package if I changed my mind, I called back less than 4 hours later to cancel after doing some research on the internet and was then told that I could NOT cancel the package despite being told otherwise by the original sales representative.
So I ended up contacting my state's Attorney General to file a complaint, and was promptly refunded the entire cost of my package - despite being told on the 2nd phone call that it was non-refundable.
Definitely NOT a reputable business IMHO.
The reviews I read indicate that the vast majority of the rooms have ventilation problems. SO many developers do not realize the major humidity difference that is found in most of Florida. When it is humid outdoors, and air conditioned indoors, along with poorly ventilated bathrooms - the potential exists for a lack of humidity differential from outdoors to indoors.
The result is mold, mildew - and the damp musty smells that result.
Developers build building in Florida that will literally rot themselves from the inside out - for the most part Disney does a good job on building for the climate, however where I have found that Disney makes their biggest moisture mistakes is cleaning of carpets and not ventilating the room properly afterward to assure the rooms do not develop a musty/moldy odor.
Anyway - back to Summer Bay - I would steer clear!
