Hi Matthew!
Welcome to planDisney.
It's always a pleasure to assist my fellow guests from the UK, and I'm excited to see 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.
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.
I have had occasional success using the Chat feature on the My Disney Experience app, so please give that a try. Sometimes a helpful Cast Member may be able to make a reservation for you.
Using an authorised Disney Travel Agent based in the US or Canada is 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'm sorry this may not be the answer you wanted, but I am hopeful you will be able to secure your place on this tour, one way or another. I feel your pain 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
