Paying separately for parking was annoying and the lot was very full. The room itself was good and clean. It would be helpful to add luggage carts near the elevator entrance.

The room was clean, bed & linens comfy. The rooms and bathrooms are a bit tired, could use some updates, but price is good and would reflect upgrades if fine… so for the money it’s all good. Shuttle service was great for an early morning flight. Would stay again.
