Just an update, we were there last month (but left early due to rain

) and we saw plenty of newer cars being let in (a couple 3rd gens came in and parked, I do not remember any 4th gens though). I guess they are not that strict anymore
They put sawhorse type barriers down the middle of the last row, I saw plenty of newer (and some old ones) parking on the other side of the barrier row
But the food changed, the 1st cruise Iplay had an outdoor grill area, with good looking food. Now they hand out wristbands to go inside to their food court, but I did not go in this time. Walked to burger king instead
