I was skeptical at first but it was alright. Took some time to get use to. Overall everything was good. The parking is the only issue, you have to park around the corner for $35.00 but if you go out more than once they charge you $10 each time you go out.

Last minute. Fit the purpose. I just don’t think it was worth the price, since I got charged with resort fees + parking wasn’t in the premises.
