The restaurant wings. If you get them with the sauce on the side they are crispy delicious! The room was clean and quiet. I did have to ask twice for conditioner as the girls be provided in the shower was empty, but they did bring it! I love that the provide the large bottles for use. It smells nice as well. We used their parking for the week we were gone and my car was just the way I left it safe and sound. Paid about 28 dollars for that service. There was cheaper parking around but this was so convenient. Also the shuttle to and from the airport were top notch and easy.

There’s something about an area that has an abundance of security & sheriff’s car with lights continually on.
