Not Django related, but well ... there you go

The short answer is: don't.

The longer answer is: Your room only holds 200 people, so at some
point someone will be out of luck. You just need to make sure that if
someone starts a serious attempt to book a seat (as opposed to just
browsing around), that he can complete the process in the assurance
that he'll get a seat/the number of seats he want. Therefor have a
'check for availability' step early (first?) in the booking process
and make a temporary reservation for that person for say 5-10 minutes
so that he can complete the booking process. Make sure to inform the
user of the duration of this temp reservation.
