Req1: We have a site where the size of the group is always 2 (a couple). So a feature/field on event page where we could set the fixed group size (instead of the max size) to 2. Then when registering the registrants can't enter the group size, and would not have the chance of registering only one person.
Req2: When dealing with couples, it would be nice to have the group information as "master" and "additional". To clarify:
1. Primary registrant enters details: name, address, phone, email etc.
2. When clicking Next, certain fields would be automatically populated based on the first entry -> for example address is already copied from the 1. registrant. Or this happens in the backround and certain fields are not visible to 2nd registrant.
Both of these would reduce the required data to be entered as well as reduces the chance of wrong data. Not critical, but it would make our site a whole lot better customer experience.
