In the past the expo has closed at 4. Hopefully they extend it this year. The actors are not in the expo. They are appear at some of the shows. There are no scheduled m&g’s unless you are able to afford the most expensive hotel package.
The EP does not get you into the expo quicker. Only the pass that comes with a package does. The lines are usualy two-six hours to get in. Once in, you have to wait in more lines for just about everything.
Assuming it is set up the same way as last year, there will be two expos. The smaller one to the left of the Jimmy ride had things like audible recall, virtual reality, and a HP
lego video game. It was less busy and even a walk in at times. I believe the Sorting Hat was a seperate line last year; you did not get to enter the expo after being sorted. It was located just outside the main expo. People waited hours for their one minute turn with the hat. It doesn’t seem like it’s worth it to me.
Some of the merchandise will be available at the main gift stores and gift stores in each HP land.
The best time to go will be Friday. Second best will be showing up to the gates at least thirty minutes early and getting in line immediately, along with everyone else.
