I could easily believe that Universal would not allow food/drinks brought into the park but that WDW would. We went to both WDW and Unviersal last November and I was very disappointed with Universal Park's employees/atmosphere. It definitely IS NOT the friendly WDW! WDW definitely seems more family oriented! What can it hurt for a family who has spent plenty $$ on tickets to bring in a bottle of water, snacks for the kiddos, etc? In November when we were there and walked through City Park to attend the other park, there was a big beer tasting event and the people tasting had more than a "taste".
I don't care if we go back to Universal again!
