I was 30 years old. I loved it at first meeting. Had the sinking feeling after leaving it on that first drip of PDD...post Disney Depression. Had a similar feeling after seeing the NY World's Fair as a boy. I knew I could never go back to the World's Fair...but I could go back to Disney and have. BTW..my daughter has that same gene...she gets depressed after leaving every time. Her first trip was at the age of 6.
