Jarbo,
The SEA may only be used for privet functions if timing allows, and if a CM is willing and able to attend the event with you and manage the arena while you are there.
First it is best to find a CM that will be able to attend your event, set up the arena, and close the arena after you are done.
Once this is done then, you can request time in one of the SEA's, on this BB. Or by PM to me.
