Yep, my son rides with my husband while I wait with my daughters, then my husband comes out and I go on with my son while my husband stays with my daughters. My son loves it cuz he gets to ride twice.
For the longest time we had avoided rides that we all could not go on, but once we started using this feature, we got to go on more "grown up" rides. My daughters are also not babies (5 and 12), but the 5 year old is often too small and the 12 year old is often just too nervous to go on some of the rides, so this has worked for us.
