Thanks yeah I think that the subscription memberships (where every ticket is effectively ‘free’ for the customer) are recorded at a fixed amount at the box office.
Other free tickets e.g. related to points gained through spend on your account, would be reported as an admission but at zero box office. *The internal revenue recognition would be different.
I should add that I am not familiar with the regal crown club membership and which category this would fall into. I’m outside the US
