I've posted before about Silliman Aquatic Center in Newark. It's a great indoor water park good for toddlers up to teens. Read Frisco Kids' review of Silliman Aquatic Center here. There's a kiddie play area (see below)
Get the deal here. The deal is offered for the next three days, and it's good through September 11, 2011. The place is open in winter, so if you want to swim in winter - here's a good option!
