I see on another site that a meet with Donald & Scrooge is available. Is this party Donald different than the one during the day? Wearing a different outfit?
Be prepared for a very long wait for this meet & greet or get in line early.
We did this two years ago during our last visit from the UK, we'd booked two parties in the same week, we usually do this as we don't like to be rushed trying to get everything done in one night.
The Donald & Scrooge M & G was taking place at Casey JR Splash & Soak, when we wandered over there it was about 8pm, the line didn't look that long so we joined it.
After 45 minutes of hardly moving a cast member walked the line to let people know that they were having problems with the Memory Maker camera's which was why the line was moving so slowly.
At that point we decided to give it a miss for that evening & come back later in the week at our next party.
Fast forward a few days & we were back, slightly further forward in the line but things were still moving painfully slowly, when we finally got into a position where we could see the characters it became clear why things were so slow.
Every meet & greet was taking in excess of 5 minutes & in some cases 10 minutes, multiple photo's were being taken, Donald & Scrooge were also spending huge amounts of time with each group, which on one hand was great when you were there with them but dragged the whole thing out, when you added in the fact that the characters were going "on break" every 30 minutes it was not unusual for the characters to meet only 3 or 4 sets of guests during each session that they were out.
By the time we realised this we had already committed so much time that if we'd walked away it would have been a huge waste of time, so we stuck it out.
It did seem to us that all of the meet & greets were being dragged out in an attempt to draw people away from the rest of what was going in the party to make it seem less crowded than it actually was.
Not trying to put you off but be prepared for a wait.
