Hey Tina,
Thanks for reaching out and for your kind words and interest in our plugins! Our plugins do generally support importing from Google Calendar, but I’m afraid there is no specific “bookings” support. With this in mind, it is unfortunately not possible to import whether the date is “booked, available, or pending” as you described in your question. 🙁
The event dates, name, location, times, etc.—all of these details are indeed “importable” with The Events Calendar and The Events Calendar iCal Importer add-on—but the “booking status” feature is not one our plugins currently provide.
Sorry to disappoint! Let me know if there is anything else I can try to help with.
Sincerely,
George
