How an evening goes
The doors open early — 1 hour 45 minutes before showtime. Those who arrive early and those who arrive on time live two different evenings. A ring of corridors around the hall holds all the food and drink, hot and cold; vegetarians and anyone with dietary needs just tell the staff.
You can only eat what's bought inside the venue; medical or religious reasons need an advance email. The whole venue takes no cash. For something more, you can buy into the Oceanbird Lounge — open bar with snacks, entry from opening, and a Sunday matinee brunch. The name borrows from the venue's only corporate partner, a Swedish company.
Once inside, it's sit, listen, and sing along. One hundred minutes, no break. The official line is that this lets you sing and dance a little longer. Want to dance? Buy a Dance Floor ticket. If you bought a seat, no one stops you standing up — just mind the people behind who can't move.
The show starts at the printed time; latecomers wait for a suitable moment to be let in, so don't cut it close. No photos, no recording, no video during those hundred minutes. The official wording: help ABBA keep the Voyage a surprise — partly for those who haven't seen it yet, partly so phone light doesn't distract those beside you.
One thing up front: no one on stage will talk to you, there's no improv, no encore, no looking into the crowd. This is a staged show, not a back-and-forth concert. If what you want is that call-and-response energy, this won't give it to you.
No need to rush out. A few steps from the exit is the light-rail station, a few stops back to central London. Friday to Sunday nights there's hot pizza, picked up only after the show — order ahead and grab it on the way out.
