Vehicle, 747

A commercial-class jumbojet, a 747 aircraft has two walkways in between three rows of built-in seating. A slight note, is that the aircraft is large enough to seat no less than 416 passengers at a time.
Clearly, the only way to acquire one of these is by purchasing the Banish point shop item, and only while the plane is grounded and close enough to the Contestant for the purchase to take place. As making something like this magically disappear would be very obvious and everyone is supposed to be an NPC, it's mostly restricted to modern worlds that have collapsed due to an apocalypse.
Besides lots of seating, the aircraft does have multiple bathrooms, a snack preparation area, cockpit, cargo hold, above-seat storage, and various emergency technologies.
