Leave before curiosity becomes endurance.
Pick three objects
A useful route offers one thing to notice at each stop without turning looking into a quiz with a right answer.
Read the room before arrival
Light, sound, crowds, seating, toilets, food, lifts, buggy storage, step-free access, and touch rules are specific.
Finish somewhere ordinary
A bench, water fountain, garden, café, or direct exit gives the group a predictable ending without requiring a shop visit.
