If this is the aqua park at the Sorgun Voyage Hotel, then great. The kids will love it. There are many different slides and even has its own track for old ladies).
The water park, like the hotel itself, is excellent. You have two fast slides, a dark fast slide, a long and spiral slide and the same but dark one. There is a scary slide on the top floor. You have to roll off the buns on them. The only drawback is that the toilet is dirty.
