Our kids LOVE this water park.  We have enjoyed it during the summer (the outside park is great) and winter for just the inside park.  The water is a bit chilly though, and our youngest one shivers the entire time.  Wish they could raise the water temp a bit especially in the winter.   As far as staying at the hotel, that was just okay.  We spent money on the wand things (for get the name of it) and that was a complete waste.  The food is very pricey, so is the buildabear area and gaming area.  Can easily drop hundreds of dollars in two days.  So, it's worth the stay for the water area but we will skip the extras in the hotel next time.
