RSVP
Deadlines, pricing & cancellation policy
Registration is where you find out who is actually coming, and the RSVP policy is where you protect the event from no-shows.
RSVP covers how people register, what they commit to, what they pay (if anything), and what happens if they cancel. A clear process here reduces the chaos of the days before the workshop: you know how many people to expect, who has dietary requirements, what questions they have, and whether the numbers still support the design.
Deadlines matter. An RSVP deadline five days before the workshop lets you confirm catering, print materials per head, and finalize room layout while there is still time to adjust. A process with no deadline leads to confirmations arriving the morning of.
For paid events, cancellation policy is part of the financial protection of the workshop. A policy that is clear in the registration (for example, full refund up to two weeks before, no refund after that) is far easier to enforce than one you try to apply retroactively.
