A couple of weeks ago I took my three oldest grandchildren to Orlando International Airport to give them a tour of the main terminal and all the shops, eateries and entertainment locations. I would say they were slightly rambunctious, though overall very well-behaved. We had a good time!
1.difficult to control or handle; wildly boisterous: a rambunctious child.
2.turbulently active and noisy: a social gathering that became rambunctious and out of hand.
