Banksy’s highly anticipated “bemusement” park, Dismaland, is set to open Saturday in London, except there’s a major problem: Huge demand from potential visitors has crashed the site. So how will fans buy tickets to see the U.K.’s self-proclaimed “disappointing" attraction?

One thing is certain: Fans will not be able to purchase tickets online for opening day. The bemusement park is “currently unable to process online ticket sales,” Dismaland wrote on its website Friday.

Instead, people will have to wait in line at the attraction. “This Saturday and Sunday August 22nd and 23rd, tickets will only be available on the door (of the portacabin on the grass opposite the site) from 9 a.m., GMT,” a statement on the site said. Ticket prices cost £3 for adults, and children under 5 enter free.

Dismaland has a maximum capacity of 2,000 people. After the limit is reached, people will be allowed in based on how many people leave. The park will stay open until 9 p.m. GMT. "This may result in some queuing and we apologize for any inconvenience,” Dismaland wrote.

Fortunately, visitors will be able to buy tickets online again starting Tuesday. Make sure you buy tickets if you want to go, because Dismaland will only be open for five weeks.

Dismaland, which promises to be a spoof of Disneyland, was able to build a fan base with the following description: “Are you looking for an alternative to the sugar-coated tedium of the average family day out? Or just somewhere a lot cheaper? Then this is the place for you. Bring the whole family to come and enjoy the latest addition to our chronic leisure surplus.”

In small writing, the description continues: “Contains uneven floor surfaces, extensive use of strobe lighting, imagery unsuitable for small children and swearing.” At the end, Dismaland added this cheeky coda: “The following are strictly prohibited in the Park-- spray paint, marker pens, knives and legal representatives of the Walt Disney Corporation.”

British graffiti artist Banksy is behind Dismaland. He is also a political activist, film director, and painter who is known for his satirical street art and dark humor.
