I would choose the Poly .
The waiting process is slightly easier from this location because it is easier to “ wait” at the quick service location until the Parade arrives.
Otherwise the waits would have to be on the boat dock at the Grand and the Contemporary Boat Dock
. Depending on the weather and having to wait and possibly stand around …. I vote the Poly . And I have done all 3 locations. And I am old too ! Haha
