Start with the bad because its important and if i can spare anyone else dealing with utter disappointment from their children....i would be happy. Check in time is 4pm . Water park closes at 4pm on most days . They are closer Monday tuesday weds. Even if its a homiday and schools closed. This was the single reason we drove many hours to go there. They said they couldnt call me to let me know because we booked through a third party ( expedia ) ive used expedia for years and have had many hotels call me for issues ahead of time with no problem. Check in women said they called others to give them the heads up but they couldnt call us . The good /decent . Breakfast was nice and included , bed comfortable and room clean. Check in staff were nice .

You can tell the hotel has seen better days! Our sink drain and shower drain did not drain well. The water park definitely needs some updates. The staff and cleanliness was great though. We saw online that there are plans to remodel, we will visit again!!
