Mde has been up and running in the UK for some time. I had all sorts of problems with virgin holidays who tried to fob me off with all sorts of reasons why my tickets didn't show. I Gave up on my so called

Disney sorted it out and I had no more problems with my booking or fast pass pre booking. I've been and come back boo, everything worked like a dream. MDE wasn't the issue, my UK travel agent was.......go straight to Disney help line, UK travel agents appear slow to adapt.
