I sometimes have clients who want to book multiple appointments with me all in one go. For example, we might schedule a couple weekly meetings. Or I'm doing a multi-part training with them. Right now, when you schedule an event, it takes you to the confirmation page, but if you wanted to schedule another event, you have to go back and find the original link (or use the back button in the browser, but I'm always nervous about that when there's form submissions involved. The easiest thing might be just a little link on the event confirmation page that says "Book another appointment?" and then a link back to the scheduler. Just make sure it doesn't sound like a reschedule option. Alternatively, on the booking page, maybe have an option for multiple selection. Like I want to book the time on Wednesday and also on Friday in one pass.
