In my dreams lol. We actually leave on the 18th but only arrive in the evening of June 19th. We have had several schedule changes to our flights and the last one was terrible, leaving us with an overnight stay at an airport hotel and a 7.5 hour layover (I had paid more for my specific flights because I'd picked a great connection time and then they changed them, the cheeky souls

) I think this is the longest journey we have ever had to Orlando by a long shot. We are doing DTD on our arrival night (which is now June 19th) and MK and Epcot on the Friday.
I managed to make one day's FP selections for June 19th today. Must have been a glitch with the app as it only allowed for Epcot and just for that one day but it's been entertaining to try envisage what must go on in the minds of the folk who designed this app
