Crowds in May are generally average to above average during the first three weeks. Between May 1-15th would be the best time to visit. Not only are the crowds the lowest of the month, but you can enjoy Epcot’s Flower and Garden Festival. Temperatures are warmer, with highs in the upper 80’s and lows in the 70’s with fewer than normal rain showers. Also, during the month of May, all four parks begin opening earlier and staying open later, with more frequent magic hours. Very few, if any, refurbishments take place during the summer months.
