We have been coming to the Hyatt Zilara for years; this was our 12th stay. The staff and food were perfection! Everyone has a great attitude. We always book a swim-up suite room. We take these short vacations due to both of us overcoming health issues, which daily swimming helps. Vacations are expensive and push our budgets, but the health benefits are intense and needed. This was the first time we had a bad experience. Unlike all 11 previous visits, the bed was very hard; the pillows were extremely heavy, and the room temperature was hot. Staff tried to fix the AC to no avail. Staff tried to make the bed softer by adding a duvet to the mattress, but it didn't work well. I've never dealt with pillows that were so heavy they were hard to lift or flip. Our wrists hurt now after the vacation. It's such an odd hotel room issue - but awful. Our room temperature at night was never below 76 degrees F - very uncomfortable. Our pool access area was at the very end of the swim-up suites. Unlike all previous trips, the pool was filthy the first two days. The staff took note and started to clean it. It was so bad we'd have to step through piles of floating hair and debris to enter the pool. The slime attached to the lounge chairs in the pool floated 2-3 inches as it floated in the pool. After a few days, staff cleaned the pool to perfection. I hope the issues were isolated to Room 101. We will return; the staff tried to fix the issues - but we returned home unrested and hurting.
