Is there a resort fee and is it already included the the nightly rate?

There is a resort fee and it is NOT included in the listed rate. Honestly their pricing is rather deceptive. You can assume you will be paying a lot more than they list.

Yes

Also they have a 50 dollar holding fee in case of charges, but you get that back at check out if no issues

But the resort fee is disclosed at reservation. Just easy to forget once checked in
