New update from Screamscape today:
June 2014 - Wizarding World of Harry Potter - DIAGON ALLEY - (5/10/14) A few more details about the Gringotts ride and Diagon Alley ride came out last night during a team member Q&A session about the new Diagon Alley area. The ride experience itself on Gringotts is said to be approximately four minutes long and as expected, the entire main queue for the attraction will be indoors.
They would not confirm or deny the revived rumors that suggest interactive wands might be sold to cause certain magical things to happen around the Wizarding World, however there was also a mention about something called “dark corners” which they would not discuss.
We’ve already seen some minor changes made to the Hogsmeade side of things, with the closure of the old Zonko’s shop (and expansion of Honeydukes), and while no major details were mentioned, management did confirm that a few more changes would be made to Hogsmeade down the line.
A question also came up regarding the transportation of strollers on the Hogwarts Express ride when traveling between the parks. Only compact fold-up strollers will be allowed onto the Hogwarts Express, however guests who have rented ECVs will have to leave it at one station and pick up another one at the other station.
An exact opening date was not given at the presentation, though a Loews chairman slipped up in a presentation the other day and mentioned that Diagon Alley would have a “mid-June” opening. This falls in line with a rumored June 20th date that I’ve heard mentioned, but again… a lot can happen between now and then and Universal isn’t going to open anything until it is ready. With that in mind, if you are just dying to see Diagon Alley (and I know thousands of you are!) keep your travel plans flexible.
