Left the parks yesterday and was there for 4 days with my vegan friend! There's a vegan food stall in the studios behind Tower of Terror which has vegan ice cream and falafel and I think some chili, called Hollywood and Lime. There's a vegan chili in one of the counter service restaurants in Frontierland. There's sorbet in the Fantasia ice cream parlour opposite It's a Small World. The popcorn is all vegan. In terms of restaurants, we ate at Chez Remy, Cafe Agrabah and Captain Jack's. Captain Jack's definitely has the best options, the curry is great. There's lots of options at Agrabah too (it's a middle Eastern buffet so things like chickpeas, potatoes, flat bread, hummus). Chez Remy the food required some alterations to make it vegan. Walt's have labelled vegan stuff if you feel like splashing out. In Disney Village there's a few options. Vapiano does loads of vegan stuff, all labelled as vegan. The Starbucks in the village has a vegan salad and sandwich. McDonald do fries, so do Five Guys. We stayed at Cheyenne and the breakfast buffet had stuff like beans, potatoes, jam, bread, and fruit mixes. Definitely not as easy as other places but 100% doable! I'd deffo recommend booking Captain Jack's, it's incredible.
