Hello
We went to the HP expo I took my 2 girls age 6&10 we all loved it. It cost us $36 because we live here now. The girls didn't really like pulling out the Mandrakes those screaming plants but that's all you can touch some things, there's no picture taking while your inside.
It's only a small exhibition but loads of props,wands,costumes e.t.c .
The gift shop was pretty expensive. We were only in there for about 1 1/2 and we walked around slowly reading everything and let people go ahead of us. They also have different scenes too we enjoyed it
