I've been informed by someone who stays in the Waterfront Chalets during their visits, that not many of the Chalets have air conditioning in the living room and kitchen areas, only in the bedrooms. She also mentioned some people leave the doors open for the breeze to go through to help cool the unit. We'll be staying in a Waterfront Chalet our next trip. I hope our unit has air conditioning in the living room and kitchen!

Edited to add:

Maybe if the living rooms/kitchens had air conditioning installed, this may eliminate the need to leave the doors open.
