Looking for a booking calendar

Hi Everyone

I am looking for a booking calendar that allows me to sync with google.
I have 3 arenas which can be hired at the same time. but If one is booked I still want the other available to be easily booked on the website by another customer for the same time

Can anyone point me in the right direction as to what calendar would be best for my needs or direct me to a tutorial

Any help is really appreciated


As far as know from the site to Google calender is possible the other way is not
( I have been asked the same thing one year ago, not sure if the Google changed something now )
