Is any of the water park outside or is it all indoors?

The hot tub is outside, but the waterpark is indoors.

The correct answer is; the hot tubs are located both inside and outside! You can exit the hot tub and enter pool, then you can swim up to the pool bar and have a beverage or drinks. Then you can exit the bar pool and go outside to relax in the out door adults hot tub! It was a relaxing weekend. Drinks in the bar pool are expensive,also must have proof of age no matter how old you are, at 56 my wife had to give them my ID before he would serve me a drink.There is a hot tub indoors and out doors, None of the water park is outside. I put photos on here somewhere...

Outside of the adult only hot tub, the park is indoors.

I do believe its indoors only.
