The park was open from 10am until 9pm but I advise you to get there early to stake out a table in a reasonably good spot. Also make sure you make it clear the table is taken or you might return to someone else sitting and your stuff moved off to the side.
When you first enter you are greeted by very friendly staff who if you are a hotel guest will provide you with a towel. (They will give you one even if you aren't staying at the hotel). Immediately in front of you is the small children's section of the park. It includes small slides water jets and a large bucket that dumps 100+ gallons of water at regular intervals. The water here is less the 6 inches deep and ideal for the little ones to sit and play.
Next you encounter the lazy river where there are ample rafts to take you on a relaxing loop around. Again some of the unpleasant people treat it was a race track and ram into you while you are floating along.
The next section is a pool 3-4 feet deep and contains three basketball hoops and ample balls for everyone to enjoy. This pool also has a jungle gym where you can ease your way across the pool suspended if you like or you can use the massive lily pad floats below to assist. Great place for the kids to enjoy themselves.
The highlight of the park is certainly the three large tube slides that take you outside the building and provide loops and moderate drops. One of the three is designed for little ones and isn't very steep and ends on a mid level and doesn't require a tube. The other two (One dark and one Opaque allowing light in) are similar in size speed and nature. These are fun and provide a little excitement for the older kids and adults.
They also have an indoor/outdoor hot tub which is a great spot to just relax.
The food is very expensive and I absolutely recommend bringing food in with you unless you are prepared to over pay. There aren't any rules about no food from outside so definitely do this.
All in all it is a great time for younger kids and adults with little ones. This isn't a park designed for adults to really enjoy but it does provide a great place to take the kids in the winter. Have reasonable expectation and you will be pleasantly surprised how much fun you can have here.
