9/10 Wonderful! (1,005 reviews)
Room was nice. Air conditioning worked well. I did not have time to try the breakfast, but others said it was good. Best part of stay was the staff. Everyone I met from desk staff to cleaning staff to kitchen staff were very warm and friendly. For the price, I would definitely stay there again.

Terrible stay…Long wait to check-in, rude front desk lady, no hand soap, not enough towels, pool was freezing so our kids couldn’t enjoy it, hot tub reeked of unusually strong chemicals, had to beg for towels…ants on the table at breakfast. Not worth the savings, don’t do it!!!!
