The hotel is a little outdated but still clean and comfortable. Every staff member we encountered was amazing! Friendly, helpful and very accommodating. The arcade needs some work with half the games out but the pool and all its features were awesome and they had a cool kids zone full of activities. Overall it was a great stay and we would definitely go again!
