The SunBreeze Hotel has a conference room. I'm not sure how large the room is though. You can email Julia and she should be able to help you. The Hotel has 39 rooms, maybe you can book the entire place for your event! See this website for more information on the hotel. Good Luck!
P.S. I will be at the SunBreeze May 5- May 12. I can check it out and give you feedback if you would like.
