When it comes to Disney Parks, none scream alone time like EPCOT and I have spent more time at this park by myself than any other park at Disney World.
You don't need a girlfriend, wife, or kids to tour the World Showcase. You can enjoy the festivals at your leisure without the stress. Fee free to eat around the world or take in a concert show. Jump into the France Pavilion for pastries, sandwiches, or even ice cream.
EPCOT offers everything and even if you want to ride the Finding Nemo ride to the end and hang out at the aquarium, go for it. You deserve it.
Every part of the park is perfect for a solo trip and I have taken the time to sit in the upper part of the Japan Pavilion and type away on my lap top while I sipped a Violet Saki.
Back in the U.K., there is a wonderful little garden where live music might be playing and you can enjoy a Guinness while you listen.
EPCOT is a wonderul solo experience but for as great as it is, I find one park to be the best of them all.
