I have one recommendation for you. FANS...and lots of them. Look at the Punta Cana airport. They keep the main check-in exceptionally cool given the heat with fans. Your check-in area was stifling, the restaurants much warmer than normal and the outside bars barely comfortable enough to sit at during the evening. Fans, fans, fans, and everywhere. Your staff begged us to write to you and ask for fans. Also in the rooms...the balcony...they could use a fan. There isn't much breeze that moves through there.
Aside from that...great room, great pools, a small casino that took my money, (and could be open longer) and solid food at every restaurant. Overall a great experience that I would come back for, but not in September. Maybe February.
Remember....fans. Did I mention fans? Ok...fans.
