JAKE!!!! I love you, too, and you've got to be the coolest kid ever for wanting to ask a question of the Disney Moms Panel. Thanks for paying us a visit!
I called
the Lego Imagination Center at Downtown Disney (407-828-0065) and talked to a very informative Lego Associate named Bill. He says that unfortunately the Batman Lego series was discontinued in 2008, and there are no more sets sold at the Lego Store at DTD.
However, Bill suggested that you come by the store the next time you're on vacation at WDW and check out the World Racers Series. It was designed in a similar way as the Batman series, and it features various vehicles such as motorcycles, race cars and boats racing in sets such as Gator Swamp, Blizzard's Peak and Desert of Destruction. Bill says that if you have an interest in the Batman Series you'll love this, and it would be your level of play! (You ought to check to see if Bill is at the Lego Store the next time you're there and mention that you were the kid that asked the question of the Moms Panel...he'll think you are a rock star!)
Thanks, again for your question...it sure was a fun one to answer and well-thought out, too! I hope your day is wonderful and your vacation magical! (Tell your mom that she's pretty special, too for giving you the opportunity!)
