“In my opinion, this hotel is geared towards family fun, with its large indoor waterpark and arcade; plus, Tony Roma's on-site provides a familiar dining option. However, some reports mention cleanliness issues and maintenance delays, which could impact the stay. It's a mixed bag best suited for those prioritizing the waterpark over pristine conditions.”
