I am planning a trip for summer '21 for me and my wife. We have tickets and can get park reservations. But it is possible that we might also take a young granddaughter with us. I won't know that in advance so I will not be able to make park reservations because she does not have park tickets. If there are no park passes left, I wonder if this is something that guest services can solve when we get to the hotel. It seems that they must have a few passes available for last-minute additions. Thoughts anyone?
