First of all: There is no other plugin that matches both the client and the admin perspective of this plugin. I have at this date tested all the other existing plugins. Just to find out that this plugin is the leader of wp booking calendars.
Second of all: When you have found the version matching your needs. You might need some help with the plugin. Their customer service are kind and fast on replies.
Last but not least: The plugin can be used for conference / meeting room booking, hotel booking or vacation house booking. With a little help from support and documentation. No coding experience requirements for using the plugin.
