I have been taking my 3 year old to Under the Sea since she was one. We usually go to the one in Culver City, which is a blast. We recently tried this one and I have to say, I like this one better and so does my daughter. This one has more things to climb on and to play with. There are 3 large slides, a play kitchen, a couple small slides, air hockey table, ride on toys, arcade games, a bounce house and much more. It also had a lot of energy because it was a little busier than the one in Culver City. The cost is $8 per child all day and adults are free. They have punch cards that give you a free visit after 8. Everyone must wear socks, which can be purchased there if you forget yours for $3. There is a nice size area with picnic tables for adults of older children to sit and read. I am in the play area the whole time because of my daughters age. You can also bring small snacks and enjoy them in this area.. If you want they will order pizza for you as well. At the end the kids get to choose a treasure from the treasure box. Just a lot of fun for little ones. This is also a perfect place for a play date.
