I’ve carried a bottle of wine that I bought at Epcot onto a Disney bus. I had no idea it wasn’t allowed. It seems strange to me that an unopened bottle of wine wouldn’t be allowed on the bus. An open bottle or glass of wine not being allowed seems more reasonable. If they don’t want people carrying unopened bottles of wine onto the buses, they should make it clear either at the stores and/or at the bus stops. We spend a lot of vacation time at Disney, and I had no idea about this rule.
The time I bought the bottle of wine (which was several years ago), I was told I couldn’t send it to the front of the park. I wanted to, lol. I was told I had to carry it, which wasn‘t a fun afternoon!
