I booked this hotel mainly for the pool and hot tub for a girls’ night. Check-in was at 4, and we were surprised to find out the hot tub closed at 6. Most hotels we’ve stayed at keep their pool areas open until 9 or 10, so this was a little disappointing.

Room was very nice. TVs wouldn’t work. Reported it to front desk and they sent signals up but didn’t work. Reported it again they said they would send someone right up and they didn’t show up until almost 6:00pm the 2nd night we were there. We told them just to forget it by then. We never got maid service. Also our safe was in the open locked position so we could not use it. Just small things but things you wouldn’t expect in such a nice place.

Check your Resort Fee carefully before checking out! I stayed for 3 nights (Jan 28th – 31st), but the hotel charged me for 4 nights of resort fees. When I pointed this out, the front desk staff insisted that charging for the checkout day was correct. This makes no sense—no hotel charges a resort fee for the day you leave. I had to ask for a manager, and it took about 30 minutes to finally get the overcharged night refunded. What's worse is that the staff member didn't even apologize or make eye contact after the mistake was found. If I hadn't checked the bill, I would have had to spend hours on the phone later to fix it. Please double-check your folio before you leave this hotel!

Disliked: Staff & service
Upon checkout, a $150 fee was added without explanation. I asked the clerk to waive it, she didn't. I asked to speak with the manager who actually could waive it but she took pleasure in refusing to waive it. This is the kind of garbage fee that the very lowest establishments force on guest. Not at all happy.
