Let me contribute my 2 cents as being an organizer for the past two Boston meets.
1. Someone needs to step up an actually book a conference room, otherwise this meet will never happen. Don't ask if a date is good, set the date and post to see who will show up. Unfortunately this cannot be me anymore since I live in Florida now.
2. If you can find a place for free, great. Else expect to shell out ~$500 for a room. Hopefully everyone is nice enough to contribute to the cost. For me, this was the case on both occasions.
3. Power will always be an issue, tell everyone to bring power strips and even better a power regulator. You can read about the issue I had with one of my amps in the 2010 meet thread.
4. I held both my meets at the Hilton in Dedham. Nice central location for those in NH and CT. Lots of space and noise isn't an issue.
5. Go to the afterparty.
If someone does decide to organize this, PM me. I have a few more tips.
