We went to to Walter Graham Aquatics Center in Vacaville, CA for a birthday party for one of the members of our Brownie troop. This facility was wonderful for adults and kids alike. There were : Two 35 ft waterslides, Children's activity area, Two low diving boards, One high dive, 25 yrd lap lanes, with diving blocks, a BBQ area, and you could rent out one of the birthday areas. The place was very clean and lots of grass areas to lounge with the family. You were able to bring in your own food and drinks too. $4.50 for kids and $5.50 for adults. The only draw back is it is only open from 1pm to 5pm. We loved it and plan on going back.
