Our A/C didn't work (late-July in NC). When I informed the front desk they said the maintenance person lived 45 min away... we had a small child with us who needed to go down for bed, so waiting 45 min just to have someone get there to look at the problem didn't feel like an option. They couldn't switch our room because they were fully booked. As a last resort, I asked if they had a portable fan we could borrow which fortunately they did.
After hearing "daddy I can't fall asleep, I'm hot" 50 times I realized I should have cut my losses at the beginning and just waited the 45 min for maintenance to arrive and hopefully fix it quickly. It made for a long, miserable night and following day.
The toilet paper holder was also loose so the roll kept falling off, and the sink drain wasn't working well.
When we checked out we were told they would be adding points to our account but of course those didn't show up in our account either.
If we hadn't experienced the broken AC issue, the facilities themselves seemed comfortable and nice. However we paid a higher price than similar hotels were offering because we were paying for the Hyatt brand. Based on our experience we realized the brand is not a reason to pay more. I would have expected a higher level of service given the price and brand.
If you have an issue with your room, just know that maintenance might not be able to arrive for at least 45 min, which may not be an issue if you plan to check in early.
