We just started DD at The Little Gym at lakeline (during the week) They offer a Saturday morning class for 19 month - 2 1/2 yr olds. I'm not sure if they have openings. DD seems to enjoy it.
In Lakeway, there's Rolly Pollies gym or Paiyh Dance Studios in the HCG. Also, there's Flipnastics in Lakeway. As far as Lakeline goes, there's a Little Gym next to Barnes and Noble. In the middle on 2222, there's JW Tumbles and the Dance Institute. HTH!
