There are many full sized taxi vans that will accommodate 12 or more passengers. There would be no need for 2 vehicles if the party secured a van and with one vehicle it should be less $$ than taking two. According to the port schedule one can access from TTOL, the Adventure of the Seas docks at approx. 7:15am. Departure is listed as 18:00/6:00pm. I would think one could be off the ship no later than 8:00am so they would have a full day, if desired, to do what they want to do.
