We have a similar scenario for one of our big events. Unfortunatley I dont think there is an easy session qty discounting option, or not one that we could find. We ended up creating multiple admission items. It can be more work but easier for the registrant to understand.
We had a
- 1 session pass, and put an advanced rule of which sessions they could choose from and only allow them to pick one
- 3 session pass, again with an advanced rule but they could choose 3
- 6 session pass with the same rule but they could pick 6 sessionsIt would depend on how many sessions you have to choose from as to how viable this is as you would need an admission item for each combination of session selections (hope that makes sense)
Good luck, and let me know if you find any other ways of achieving a good ourtcome
