Park, lands, attractions and entertainment are subject to change or closure, including for capacity, refurbishing, weather, force majeure, and special events.
The contract's force majeure clause allowed for cancellation of the contract without costs if the project lagged by more than 24 months due to a failure to obtain municipal permits.
However, force majeure clauses are used in contracts because the only similar common law concept -- the doctrine of frustration -is of limited application.
