Hi Tanya,
Welcome back to the Disney Parks Moms Panel!
Park hours are currently available through April 18, 2019, so May hours should be available soon. When I called to check with technical support, the cast member I spoke with said park hours are typically available about six months in advance. So, May hours should be visible in early November. Just know that, even after park hours are released, continue to check them periodically. After I made our plans for our last family trip, a few months later, new early morning Extra Magic Hours were added to Disney's Hollywood Studios just before Toy Story Land opened.
To check park hours, go the Walt Disney World homepage, click on the Parks and Tickets link and then, from the UK site, click on the link for
Today's Opening Hours under Park Hours. From there, you should be able to use the calendar feature to scroll to additional months. If you are using the My Disney Experience Mobile App, you should see a link for Park Hours after you click on the icon shaped like a house.
Tanya, when I am planning and cannot see the park hours just yet for our visit, I typically check the hours for a few weeks prior to our visit. We love to do pre-park opening dining reservations when the parks do not have early morning
Extra Magic Hours, so knowing those park hours is important! Occasionally, I have had to switch a dining reservation once the park hours for the dates of our trip were released, but have been able to do so unless it is Be Our Guest Restaurant or Cinderella's Royal Table. Once I book those, I normally keep those reservations no matter what the park hours are!
Magic, memories and Minnie Mouse hugs,
Donyell
