Hi Fajer.
Congratulations on your upcoming Walt Disney World vacation! You're going to create such amazing memories together at this magical place!
If you have a 5-day Park Ticket, keep in mind that there is no admission or park ticket required to go to Downtown Disney!
I'd recommend that you consider visiting Downtown Disney at the end of your day at Disney's Animal Kingdom, since the park closes earlier than the other parks. Consider reserving dinner at one of the many, great
Downtown Disney dining locations and then stroll around visiting the many
fun shops. After spending a few hours there for an evening, you'll know if you want to return there another day, or not. Personally, I don't think you need a full day at Downtown Disney, especially with young children. You'd be able to use that extra day to consider another day at your family's favourite park, trying out Epcot or even just enjoying some down time at your resort!
I hope you'll visit me again with more great questions so that I can help your family plan the very best experience you can possibly have!
Wishing you a Magical time as you plan for your family's first Walt Disney World vacation Fajer.
