Conflicting or incomplete policy evidence
The source records disagree or leave a qualification open. Both recorded statements remain visible; this page does not choose a more permissive limit.
- Separate bag-policy page was not readable (520); its prior exhibition-only wording was not refreshed. Formal current policy requires deposit on arrival.
Before leaving
- Open the official source and check your route, ticket, event or exhibition.
- Measure your bag when packed, including protruding pockets and other parts counted by the operator.
- Check the number of bags, material or transparency requirements, and any storage conditions.
- Ask the operator about exceptions and accessibility or medical needs when relevant.
Passing a numerical size check does not confirm boarding or admission. Event-specific rules, staffing and available storage can change the outcome.
