I think my Uncle Phil is standing in the same spot as he was 36 years prior when he took the shot of my parents. There were many families sitting and eating on the patio - we just opted to stand further down a bit.... note the Contemporary hotel in both shots and Space Mountain in our picture.
BTW - in the picture of my parents, everyone seems to be in swimming suits....EXCEPT for the lady in a purple leisure suit! Either everyone else was cold... or she was totally burning up in that thing!!!
