Plugin for scheduling

Hey everyone, I am trying to find the best scheduling plugin for my unique needs. I am running a web site for a local nightclub and they have VIP tables. These tables can be reserved for groups by one individual. What I want to know is if there is a plugin out there that supports this workflow.

User XYZ enters the VIP reservation system and is presented with a calendar. They click on the date and the table sections appear, showing which if any of the tables are available. They can register a VIP reservation which is pending until the manager approves their booking.
