A class arrives, splits into teams, and works your rooms in a set order looking for the answers. The trail is mounted once and runs for every group that books after it.
Free — one trail, 10 players, no card.

The questions are about the things you already have on the wall. Your education lead writes them in an hour with the AI assistant they already use.
An answer card cannot be guessed from a phone. To move on, a team has to find the object and read what is next to it.
Mount the codes once and every school group that comes after plays the same trail. There is nothing for your staff to set up on the day.
A 10:30 arrival and a 12:15 coach, which is the slot most trips actually book.
Teams of four or five, one phone each — a teacher's or a helper's. Typing a team name is the whole of joining, so a class is playing about four minutes after the coats are off.
Teams move through the trail in the order you set. Because a card unlocks only when the ones before it are done, thirty children are not all standing at the same case.
Points from answers, treasure and beaten monsters. The board is live, so the last ten minutes are a real finish rather than a slow drift to the shop.
Nothing is dismantled. The next school books the same trail and your staff do nothing on the day.
Most venues host the same two or three year groups over and over. A trail is written for one of them — the reading level, the vocabulary, and the objects that are on their syllabus — and a second trail for another costs an hour, not a rebuild. A Key Stage 2 group and a sixth form can walk the same rooms on different trails, on the same mounted codes.
