Our kids are getting into Harry Potter, so took a detour during our London sightseeing trip to Kings Cross to see Platform 9 3/4. Even at about 09:00 on a Sunday morning the queue was already filling up. The kids were keen to join and in we waited about an hour for the photo op and another 15 mins browsing the store. Contrary to some other reviews there’s no obligation to buy the professional photos they take and you’re perfectly at liberty to take your own photos when you get to the front of the queue.

unless you get in the queue for a photo you can’t actually see the trolley, only the sign. and if you want a photo you have to wait in a massive queue and take it in front of a massive crowd of people. the shop was very busy, very small, and very overpriced (typical for a harry potter attraction though). no space to queue for the till so it’s a bit of a free for all and you’re not allowed to have backpacks on, they must be carried. so if you’re in london just to see harry potter sights, for sure this is a good one. but if you’re travelling through king’s cross and want to stop by on the way past, maybe come back another time.

Stopped by on my way to St. Pancras. Cool place and shop, but extremely busy. I didn't bother getting in line to take my photo with the Harry Potter baggage cart, the line was too long. The shop was extremely busy, but the staff got us in and out efficiently.

Surely a temporary screen would stop persons blocking the accessible lounge. Security are not effective in stopping the crowds. The screen could have the Glenfinnan viaduct on the photoshoot side and be blank on lounge side to stop the crowds and save on security guards. Just saying.

We expected a small queue, but it turned out that it was about an hour long, and managed by WB staff. It was fairly well organised, just long. At the front of the queue, the staff had scarves and wands to use as props, and they arranged each family into a “pose” to take an official photo, which you can choose to buy or not. You can also take your own photos. The posing did mean that the whole thing took longer than it needed to, which was a bit frustrating. The staff were friendly and helpful, though.

Been threatening to drop in for years but never quite made it. On approach you cannot help but notice the 1000 strong queue of Japanese and Chinese desperate to get the obligatory picture with the trolley in the wall. The shop has an amazing stock of gifts and the staff were everywhere so no danger of struggling for service. Amazing stick of wands! 2000 plus I was informed. Anyway enchanting little shop.
