OK, I just made my checklist and got my hotel info all straightened out.
Seems that I am going to be in two different hotels in the 6 days I'm going to be there. The good guys from Hero Envy are splitting a room with us from wed-sun morning. The "Sandwich days" (Tuesday and Sunday nights) are at another hotel equidistant from the convention center, just in the exact opposite direction.
So hotel: check
Flight back home: check
Have not heard from the publisher that they received my book.....
