Please help fulfil a dying wish

At the HoneyRose Foundation, we organise wishes for adults (and their families) who have a terminal or life threatening illness.
We have had a request from a gentleman with Motor Neurone Disease.  He is deteriorating rapidly and wants to spend one last quality time with his family whilst he still can.  He would dearly love to take his wife and 3 children - 20, 18 and 8 to the Premiere of Toy Story 4 in Leicester Square on 21st June 2019.  His children grew up watching the previous Toy Story films and they all share special memories of watching them together as a family.  He would like to re-create this one last time.
Tickets to the premiere cost £3999 +VAT!  The company issuing the tickets have offered us a discount of £1000 per ticket.  Whilst this is very generous of them, the total cost of the 5 tickets is still £15000+VAT.  This takes us way beyond the budget we have for each wish.
This is where we are asking for your help.  Could you donate and help us to reach the target so that we can give this gentleman his final wish with his family?  Time is limited and we would appreciate any support that you can give - thank you!
