I believe only unit 52 has A/C in both the living area and the bedroom. ALL of the units have A/C in the bedroom. We have only stayed in that unit once (last November), but have stayed in the Waterfront units yearly for the past 8 years or so. To be honest, we didn't use the living area A/C that much since the ocean breezes are plenty to keep it cool. There are enough windows in the living area to get a good cross-breeze. You can request a specific unit when you make your reservation, but they will not guarantee that you will get that unit.
