"The bathroom body wash dispensers and lotion were empty. The shuttle service stated shuttle to local area. When asked shuttle driver he said yes but the front desk stated no. Change your website to reflect airport only. Never asked about our stay. Toilet paper and towels were overlooked. Dinner was good breakfast was expensive for what was offered."
