None of you were any help!
I decided against Delaware park because of the longer drive and less cash game options should I busto.
I decided on SugarHouse when a friend on Facebook said the prize pool would hit $10k and I called Harrah's and the person who answered seemed non-committal about it even running.
SugarHouse didn't hit $10k though it made the guarantee. We wound up doing an 8-way ICM chop. I was second in chips and got essentially third place money. I also played well, I thought - made good decisions that allowed me to survive a short stack until I got some hands at the end.
