Nice hotel. Great location. Nice room. Pictures made hotel seem like it was so much more. It was just one small hallway. Nothing more. Very disappointed with the lobby. I thought by the pictures I was getting so much more! Payed a $150 resort fee for two night. There was absolutely no resort and no resort benefits. That was purely a money grab. Didn’t even get my room cleaned each day. Nice room. Nice hotel. Just less that I thought!
