Hi Emma!
Welcome to planDisney.
It's always a pleasure to assist my fellow guests from the UK, and I'm assuming you are now within your 60-day window to enable you to make certain reservations for your holiday. Specifically, dining reservations can now be booked. Your holiday is just around the corner!
Unfortunately, certain
Special Events and Tours that require pre-payment are currently not available to be reserved in advance from the UK, and this includes the
Wild Africa Trek. As soon as you arrive in the US you can access online booking for this on your My Disney Experience app, but if it's fully booked already please remember that cancellations do occur so it's always worth checking availability. Any Guest Relations location will also help with making bookings for this amazing tour.
If you access the Chat feature on the My Disney Experience app you
might have some success with making your booking, so please give that a try. It is sporadic, but sometimes a helpful Cast Member may be able to make a reservation for you.
Using the services of an authorised Disney Travel Agent based in the US or Canada this may be another possibility for booking your tour. It must be stressed that you use an
authorised Disney vacation planner because there are many travel agents out there who are unauthorised.
My friend and planDisney panelist Ashley gave this detailed answer to assist with finding an authorised planner.I know this may not be the answer you wanted, and I am sorry about that, but I am hopeful you will be able to secure your place on this tour, one way or another. I do understand your frustration because I have experienced the same issues with making reservations from the UK.
Please come back and visit us if you have any further questions, and you can
send me a direct question if you wish. We are always happy to help you plan your magical holiday to Walt Disney World!
Sue
