I don't know if I would go out of my way to stop there. If you are eating at one of the fine restaurants, or even just getting a slice of pizza or something from the bakery/ice cream shop, it's worth hanging out for a bit. Definitely plan some time if you are going to stop by one of the Epcot area resorts or going from Epcot to MGM. If you are so inclined, you can rent one of the surrey bikes. Keep in mind that the street entertainers and carnival games aren't open every day of the week. They are definitely open on the weekend, but I know in the past they closed down at least a couple of days during the week.
