It's at the convention center, so there is no hotel atttahed. The convention center is in Raritan Center, so if you look on the map you will see a few hotels in the complex. I'm not sure if they have availability anymore, you will have to check.  

I'll be there, but I don't know of any groups. Feel free to message or email if you want to meet up and say hi. I will be there Friday night and possibly Satruday.
