My kids love thier crocs. I love them at the parks, mainly for the water issue...
Most of the parks will have a water feature of some type for the kids to run aorund in, but they still have to wear shoes, so if you don't happen to have a spare pair of shoes in the stroller, you kiddos have wet shoes all day. same thing goes for those lovely Florida Downpours. Your poncho will keep you dry, but what about your feet?
This trip we are trying out the crocklings, I have heard good things about them, and that they can stay on a little better. we had a few issues with DD kicking off her shoes while in the backpack.
