Flower & Garden Festival starts three-month run at Epcot

I love F&W but Epcot always looks its best during F&G, I wish those topiaries stayed up all year, glad I'll be going in May to see them again.

My kid is always excited about the temporary playground behind Imagination. And yes, it really is striking. It also means that some portion of the extra food stands are in play for about 2/3 of the year, now that they've added the arts festival.

We visit in February, and we always get a little jealous seeing the preparations for the Flower & Garden Festival. One of these years we'll make a point to go. (Seems like we have a three month stretch to work that in now)
In the meantime we thought the inaugural Arts Festival was fun. Many of the artists displayed work that was their interpretation of Disney characters or scenes. They also had photo pass photog opportunities along World Showcase where you could climb into giant 3D versions of famous paintings and pose. We were drunk enough to have a really good time with all that and some of our pics were hilarious.
Anyway, festivals sure are popular at EPCOT and it's the perfect space to hold one, if not many. If Disney is smart they'll figure out a way to fill all 365 days with something.

For most part, the only festival-free time periods are the high demand times between mid-November and the New Year and the summer months. And if you argue that the winter holiday activities are a bit of a pseudo-festival, then the only time is the summer when they definitely don't need the festivals to push attendance.
