This is when we ALWAYS go! DH and I love Epcot anyway, but with all the topiaries and flowers it transforms into a beautiful park! We go in early May and the crowds are minimal - the longest we waited without a fast pass last year was 30 minutes for TOT and Winnie the Pooh. Otherwise, it's pretty much a walk on (obviously with FP). And the weather is perfect, too. Highs in the mid 80s usually, but one day I think we did hit 90.
