Are you talking about separate transportation, your DH in one vehicle and you and DD in another? It might work but would be tight. If you get to the gate on time around 2 o’clock, you still have to deplane and walk to the little train that will take you to the main terminal, where y’all would all go down to 2nd floor to baggage claim. You and DD could walk straight out the door there and get a rideshare or taxi, leaving DH to wait for baggage. But the ride to WDW is a good 30 minutes from MCO, sometimes longer depending on traffic, so I wouldn’t expect to arrive at the water park until 3 or 3:30. If any delays anywhere, could be later.
But then again, the water park is free, so no penalty if you don’t make it, right? Nothing ventured, nothing gained!
