Thanks for the suggestions. Yes - will def take time getting off ship - but that's still no later than 10. There are no other airlines that fly direct from FLL. As for uber to a playground - will have luggage - only carryons, but still involves suitcases. But that's a maybe - is there some kind of special playground in Dania beach?
As for the lounge, I have Amex Platinum - but it's my kids & grandkid who will be making the flight, and they don't.
