Looking for a user friendly excel database to prepare conference room layouts and seating chart to hosting venue of large groups (in the hundreds of attendees). User would like to input unique information for each event (ex. size of room, number of guests, types of tables available, etc.). Assume all the necessary data is available. In return, they are looking for the following: 1. A printable optimized layout depicting the arrangement of tables within the space to be given to venue ahead of time for set up 2. Seating chart allowing groups (anywhere from 1-20) to sit together Other considerations: 1. Desire a random arrangement of tables (no patterns) to represent realistic learning environment 2.

Groups will not be defined by unique member but rather group number ex. \'Group 1 - 12 people\'. Each member of that group can be represented by a 1. Happy to provide any other necessary details or information regarding objectives.
