Warning: just spent the last few days at the beautiful JW Marriott property in Orlando. I can not say enough about the accommodating and professional staff . HOWEVER, they are having major issues keeping the rooms at a cool temperature. Hallways and main areas can be warm. I switched room several times.
That is a big difference in temperature.
Somewhat related: On my recent stay at the ritz pentagon city one of the people in the club level was telling me about how the week before my stay, their AC took a poop, and they had their maintenance flushing every room constantly to keep them cool. lol. I think it's just something that happens when it gets hot out. AC units struggle.
Happy to hear you got your room fixed =]
