Hey Mark and thanks for getting in touch!
Our plugins aren’t very good for booking places (e.g. hotels) but are better instead for selling admission to an event (i.e. concerts, classes). Our Event Tickets plugin allows you to set up RSVPs for events and our Event Tickets Plus plugin allows you to create and sell tickets for those events. You can set a maximum number of tickets for each event and people can return their purchases, but I’m afraid the plugins will not automatically notify the next person in line for a ticket, should there be people in reserve.
Does this help answer your questions? Please let me know. 🙂
Cheers,
Geoff
