The plugin I wrote a while ago and wrote about a while ago – WooCommerce Bookings Dropdown is now in the WordPress plugin repo so you guys can download and use it as you see fit at https://wordpress.org/plugins/woo-bookings-dropdown/. You can submit bugs or support requests here, or on the WordPress support forums.
