Chair in front the desk look like someone went to the bathroom in it and was NEVER cleaned during our week long stay. Plus 20.00 a day to park and 35.00 a day resort fee was nothing but a joke. We won't be back.

The hotel was nice, the resort fees were unexpected and annoying whenever it showed resort fees already being paid through Expedia. They also do not use bags for the trash cans in the room which is unsanitary to me. The bed was hard. The views were beautiful though. Staff were friendly.
