On the subject of hotels:
Here is a rough compliation of some local hotels from the NJ FIRST website (I wrote the page, so let me know if you need more help/information):

Secondly, if you want to look for your own hotels, check out those in the Princeton/Lawrenceville area. They are likely to be the most convient and safe place for your team to stay. =)
Feel free to PM me if you have any questions, or shoot me an email and I will get your questions answered (if I can't answer them myself):
