Bookings Calendar? Google Calendar works very well for this, but obviously it doesn't allow the visitor to make a booking ... It just allows them to see the current bookings ...
You will not be able to embed a Google Calender into Imagevue, and if you could, I don't think it would be as functional as Googles own proprietary Calendar pages ... The best thing to do, is simply have a link in Imagevue in the menu or anywhere else "Booking Calendar", which opens a new window (or popup) with your Google Calendar. You can grab the entire calendar for example like this:
