Google Calendar Key to Our Website

Our Guild needed a reservation system for a specialized wood working tool we just purchased. Our Guild operates 7 days a week and every day can have different hours based on the volunteer foremen availability.
The Beauty of this plugin is that it works off of Google Calendar where we maintain our Shop Schedule. All other booking programs I tested had a fixed work schedule based on repeating days, weeks or months. This meant we would have to setup each day as a special due to the fact that we do not have a repeating schedule. With TheBooking we just copy our Google Shop Calendar to our reservation calendar and name it accordingly.
This plugin author has a premium plugin on CodeCanyon called TeamBooking that appears to be a similar program on steroids. It has the same Google calendar support and great ratings so we will probably buy and use that version.
