Texas Jumping Beans has become the birthday party destination of choice for our kids (we had my son's party there yesterday afternoon). We have had four parties there so far, and it's still tons of fun for all of us.
There are about eight to ten very large inflatable "jumpers" (hence the name). They change them out pretty regularly. Yesterday, during our visit, there was a jumper shaped like a pirate ship, and another like a long train with an obstacle course inside. They also have a large inflatable slide, which is where the kids tend to congregate most often. With the new addition of about 30-40 rubber balls that are about the size of dodgeballs but very lightweight, it made it even more fun this time around.
I like the fact that weekday afternoon parties are priced very reasonably (currently $150), and this basically reserves the facility for your party only. We seek this option since it makes it easier to keep track of the kids. Adults can join in the fun, too! The cost includes the use of a party room and about four hours of time with up to 25 kids.
If you decide to visit or book a party, make sure to let your guests know that socks are required. If you happen to forget, though, they will sell you a pair for only $3.00.
Bruce, the owner/manager, is always friendly and happy to help. In our case, everyone usually leaves tired and happy. I cannot recommend this place enough. Bruce even has a deal with a local pizza place and he helps to estimate how much you will need after everyone arrives. He then places the order, and you pay for everything before you leave. It makes planning so much easier, since all we had to bring was drinks, gifts, and a cake with plates, etc.
Texas Jumping Beans is not just for parties. They offer a daily rate of $7.00 per kid, and monthly passes which cost $39.95 for the first child, $20.00 for a second child, and FREE after that. In other words, if you have three kids (which we do), you can pay about $60.00/month and go an unlimited number of times.
Located in the Round Rock area, it is a little tough to find on the first trip, since it is slightly off the beaten path. I would recommend calling ahead for directions at 512-252-1980 or visiting their website at http://www.texasjumpingbeans.com/. They are located at 16708 Picadilly Court, near the intersection of Picadilly and Royston Lane.
