Disney released the March 2016 operating schedule at the usual link: http://media.disneywebcontent.com/StaticFiles/ParkHours/WDWTravelAgent_march.pdf. Click “refresh” on your browser to load the newest version.
This year, the earlier in March you can go, the better. And if you’re flexible with your dates, I’d look at a trip that ends no later than March 5th if possible. Once March 6th arrives, you’ve got the state of Texas inbound. March 13th-19th looks to be the second best week to visit with a lull in spring breaks. You’re still paying Peak Season prices to stay at Disney resorts, but the crowds will be more of a “manageable” above average instead of a “what were we thinking” above average. Easter pricing and holiday crowds arrive on March 20th and continue through the week after Easter Sunday on April 2nd. This is one of the busiest and most expensive 2-week periods at Walt Disney World.
The rest of April should see below average to average level crowds and temperatures that are comfortable, but continue to heat up. At the end of March, the average high is 75 and the average low is 55. By the end of April, you’re looking at highs in the low 80s and lows in the low 60s. Then by the end of May, it’s high 80s and mid-60s.
Schedule-wise, nothing really sticks out, other than Disney’s annoyingly conservative operating hours in their initial release. You can check out March 2015’s final operating schedule here to get an idea about what to expect. Expect Animal Kingdom to open at 8am during the busier spring break weeks and stay open until 7pm or 8pm. Epcot should continue its usual 9am-9pm schedule. Magic Kingdom will open at 8am most days and close between 11pm and 1am. Hollywood Studios should be open from 8am or 9am to 9:30pm daily.
Currently, there are no Fantasmic shows scheduled in February or March, but I would still expect them to be added in the future. There is of course a lot of chatter going on about what’s coming to the Studios, and while Tower of Terror and Rock ‘n’ Roller Coaster are assuredly “safe,” there’s some talk about a daytime show coming to the Fantasmic theater and Beauty and the Beast switching out for a dated show from the Cruise Line. With so much already removed from the Studios, it’s hard to imagine Fantasmic going dark for months on end on top of it. But as of now it’s not on the schedule.
