Video game fans wondering how they can check out the Nintendo San Francisco grand opening now have an answer. The new outpost for all things Mario and company is set to open May 15, but to come inside, customers will have to reserve a slot, according to the Nintendo website.

To do that, visitors need a Nintendo Account to grab a Warp Pipe Pass. Creating an account is free, and it shouldn’t be a problem for those who own a Nintendo Switch or for people who have bought items on the company’s website.

Once they’re signed in. They need to hit up this event site at 9 a.m. PDT May 1. That’s when reservations will be accepted. Tickets are available on a first-come, first-served basis, and they run from May 15 to May 18. The time slots are available at these times.

May 15 – 12:30 p.m. to 6:30 p.m.
May 16 – 10 a.m. to 6:30 p.m.
May 17 – 10 a.m. to 6:30 p.m.
May 18 – 11 a.m. to 4:30 p.m.

According to Nintendo’s website, “group reservations can be made using a Nintendo Account family group for up to 4 people.” That’s one Nintendo account holder and three other family members who must haveNintendo Account linked to a Nitnendo Account family group. Children 6 and younger don’t need an individual Warp Pipe Pass and don’t need a Nintendo Account.

Nintendo recommends that those with a reservation line up no earlier than 1 hour before their timeslot at 331 Powell St. on Union Square. Once exiting the store, customers can’t come back in on the grand opening weekend.
