To use the equipment function we are tied to use service calendars, groups and service menu. However, even after activating multiple attendees function it only allows a maximum of 5 per reserve. I'm implementing these calendars for entrance tickets sales based on available equipment and this limit has stop me for been able to continue.

All other calendar types allow you to setup the maximum amount of attendees per reserve slot under availability don't know why they remove that form service calendars.
