Hi there, Cristine!
May is such a great time of the year to visit the Walt Disney World Resort as the weather is still fairly mild.
When I look at the
online calendar for the month of May, I'm not seeing that the Park hours have been posted yet for May 31st. If you click on the link above, you'll see the date at the top of your page. The day/date will turn blue if you hover your mouse over it and if you click on it, a little calendar will appear. There, you can scroll to your desired month and the dates that have a posted schedule will appear in blue.
Schedules are typically posted six months in advance, so it should be available in the next couple of weeks. Once the schedule has been posted for that day, you'll be able to see any scheduled events such as parade and fireworks times.
Thanks so much for stopping by the Disney Parks Moms Panel with your question, Cristine, and I sure hope this helps!
Please let us know if we can assist with any other questions you have.
Wishing you and your family a Pixie Dusted vacation!
