8'x30" tables - These tables will not fit across the front of an 8x8' space.  If you want a table in an 8x8' booth, it must be placed the long way or across the back of the booth.
 
If you want to make an "L" with tables you will need to bring your own 2x4 foot tables. Using two standard 8-foot tables  will exceed your space allowance by 6 inches. as they are 2 1/2 feet wide.
