Booking Hour Test
Booking Hour is free appointment booking plugin that allows setting up a fully-featured automated booking system on your WordPress website. The paid version would be needed to define services with different options for quantities such as pickleball versus tennis and is also needed for integration with payments. The paid option is also needed to customize the information entered into the form. The cost for the paid version is $72 a year. This plugin also has an option to easily display the list of currently booked reservations on the website front end. (The information displayed will be able to be customized more under the paid version of the plugin.) Currently I like this plugin the best of all tested as far as the interface and ease of setup.
