If you have 4 people coming together, then you get a discounted price.
Another question we get on this: If you have 5 or 6 people, etc. -- all 5 or 6 would go at the reduced rate. It doesn't have to be exactly 4.
Look forward to seeing you. Things are filling up pretty quickly. Wouldn't be surprised if at least one of the locales sells out in February (even though events aren't until April). For folks who know they want to come but maybe aren't sure exactly who'll be coming with, etc, I'd suggest booking the slots now. We can always change the details later.
