8/10 Good
"Overall, it was a wonderful and beautiful place to stay. The main downside was that our elevator was not working the entire 6 days we were here and having to pay $73/day in resort fees makes me think they should have fixed it promptly. We had to climb 4 flights of stairs every time we left our room. Also be warned that they put a $200 hold per night on your credit card which I was not aware of. So $1000 was immediately taken from my bank account which I had intended to use for spending money. The staff were great. Thanks"
