With Google Calendar, you can flexibly import external calendars and display multiple calendars on a website. If you are taking bookings from multiple platforms it makes sense to integrate all the bookings into a single calendar. While platforms like VBRO and ABNB allow calendar syncronisation, which prevents double booking, they don’t all offer an embed option.
There is a bit of manual labour involved in keeping a Google Calendar safe. By using the public and private visibility options carefully, you avoid acidentally exposing customer data publicly, illustrated in the example above. By default an entry is private, until you mark it public or “busy”.
If you’d rather avoid the platforms and like using email to arrange and confirm bookings, this is a convenient and economical solution, which saves a good amount on transaction fees.
