We are in the same boat - last minute trip next week (work is sending me, so I can't complain on that end) we will only have one MK day (Thursday, AM EMH day) and while we ARE staying on-site, we booked at the 30 day window so have basically zero shot at A&E (the ONLY thing my 3.5 year old daughter wants to do). She is just not capable of waiting in a line for an hour or more so unless standby is like 45 minutes or under, we are going to have to hope she's satisfied with the singalong. Not a trip-ruiner, for sure, but would definitely be a big let down, so I want to do whatever I can to get her in to see them. Happy to split up from the rest of our party and just have the two of us go, but really haven't seen anything other than "run at rope drop" and "good luck" on any of the searches I've done (here or elsewhere). Doesn't seem like there are any great times to try, and we went for EMH last year and were towards the front of the pack (first ones on Dumbo and Barnstormer) and when we walked by Princess Fairytale Hall, the wait time was at 300 minutes within MOMENTS of park opening. I will, of course, keep trying for FP+ and will see if the concierge sees any availability when we are there but I'm still hoping to find a "best of the worst" wait time for standby.
