If you have lodging for people and a space to train, that's more than enough. Those of us who attended at Tony's gym had to book hotels (though I don't think any of us would complain about that). If we could meet each other and train/exchange ideas without paying for lodging, I'm sure you'd have plenty volunteers on here to attend. You're more than free to take control over organizing...but if you want to host a meetup, and want someone else to organize/find out who's up for the visit and attending, let me know. I can't host, but can do any of the grunt work needed.
And this meetup was so helpful for all of us I think it's definitely worth pursuing more in the future.
