FYI if you are planning on using Southwest Airlines for the convention or for travel anywhere, you may want to download the "ding" program. I had already booked my airfare for the convention (for $296.00) and thru the "ding" specials I was able to save $148.00 today. Even though my original purchase was non refundable, I will have funds for another trip already paid for. Most likely back to Vegas later in the year.
My convention trip now stands at $248.00 for (3 nites) hotel and airfare.
All I can say is SWEEEETTTTTTTTTT

I hope this helps someone
