ScheduleOnce can be used as a great activity booking system. For each activity you create a MeetMe pages – This is the page that people will use when they want to book the activity. If you want to have each activity on a separate page you can just leave things as is but if you want to have all activities on one page and have people select the activity and then book it this is possible as well.
You can also book each activity in a separate calendar or you can book them all in the same calendar, it really depends on your needs and if all activities belong to one person or more. If each activity is different you can have different settings for it such as duration, availability and even a different scheduling process. ScheduleOnce is so powerful and flexible that there are no constraints to hold you back.
So whatever your activities are, the next time you need an activity booking system remember ScheduleOnce and give it a try. You will be happy you did.
