When staying at the Stateside hotel, there are no amenities included at all, expect for free wi-if, hence the cheap price of a room.
If you want access to the water park, it’s extra and you have to drive to the Jay hotel on property where the water park is located.
If you are staying for any length of time be prepared to eat at the one restaurant in the hotel, or drive to the Jay and eat at one of the restaurants there. There is nothing local, be prepared to drive a distance for restaurants or stock up on supplies, unless the general store on property doesn’t have what you need,
