Getting In

Update: In order to get into Harry Potter Land at peak periods you now need a ticket. This can be obtained from a new area in Jurassic Park where you can get a ticket with a time you can enter the land in. Pretty much like a Disney Fastpass. So getting in is now easy, but be prepared queues for the rides can be pretty long.

Olivander's

Olivanders is both a show and an shop. There are 2 entrances. The way in for the show is from the top of the main street, and there is a special queueing area near where the entertainment takes place. This moves very very slowly and the show is only a few minutes and involves just one of the audience getting a wand chosen for them. In summary, I wouldnt queue for a long time for this, but young children will enjoy the show.

The other enterance to the shop is from the back, and there is a queue for this as well! The shop isnt very big, and Universal soon realised that the demand for wands was causing the shop to overload. Therefore you can now buy wands from a cart at the top of the street near the castle.

Showtime!

There are various shows at the display area near the top of the street. The singing toads are real fun!
