A multi-attraction pass could hold several entitlements under one purchase. The important question is what each entitlement permits: one visit, repeated visits, a timed session or a choice from a defined group.
Each participating attraction needs a way to validate its own part of the pass. Shared reporting should reveal only the information partners require. Settlement rules need agreement where income is divided according to visits, fixed allocations or another commercial arrangement.
Pilot a small group of attractions and test partial use, expiry and a venue closure. A visitor should be able to see what remains available without interpreting internal accounting rules. If some attractions require a separate reservation, the pass must explain that clearly rather than implying that purchase guarantees immediate entry everywhere.
