Good evening everyone!
Thanks to the CDT Agents that have responded with excellent answers!
To shed a little light on why I scheduled the events the way they are has to do with previous attendance numbers for each day. In addition, there will be some players that want to jump straight into SR5 with pre-gens, so to satisfy our varied fanbase, I scheduled Welcomes and SRMs/CMPs concurrently. Not to forget, this is the first time that Origins has seen Welcome events; we started at GenCon 2012 and have continued running them through each subsequent convention of which I've had a part in planning. They have been a huge success.
Our GMs may (and usually do) accept a 7th player with generic tickets as long as they are comfortable doing so. An 8th player is only accepted under very specific conditions.
Each time slot (except Wed at 1400) has what we call a Floating GM in the event we have a large number of players show up with generic tickets. Depending on the players' desires (and previous/planned events), the Floating GM might run another Welcome, an SRM, or a CMP. Some of the GMs are so accomodating, that, even if they are not the scheduled Floating GM, they will run a pick up game for players...those are truly the superstar CDT Agents!
A note as to why only 6 players instead of more at a Welcome event...well, there's only one GM to assist the players in creating characters for a brand new edition...that is a lot of work...but as I mentioned before, the GM can (and probably will) accept more. We want to make sure that all our fans receive the attention and quality they deserve from our team!
We will do what we can to accomodate you and try to make your experience the best possible. If you have problems, please try to work it out with your CDT Agent, if that fails, come to the Room Captain (at the CDT RPG HQ table in the room), or please find me!
