I completely disagree with you bn.
First of all, to answer your first question, I didn't want to wait until later this fall to obtain answers to very basic questions from josh/mirai.
Your second point, who is going to budge first. Me, who is a potential client (customer) but I want to vet out mirai if their itinerary and fees fit in my budget and education needs; or, mirai, who wants to play "hide & seek" with his marketing cards. Qualify me upfront so I'm not wasting my time and mirai is not wasting their time. Sales 101.
Third, your statement, "how much info do I (mirai) want to provide to satisfy idle curiosity or to inform my competitors about my programs"? Do you really think Ryan stays up at night worrying about his competition? He sets the bar!
"how much info do I (mirai) want to provide to satisfy idle curiosity": Have mirai post last years info once and you have satisfied a majority of inquiries. I would have been very happy with mirai's information from last year to give me an estimate. Chicago1980 provided me the information in an earlier post to give me an idea of mirai's cost and itinerary. Big thanks to him.
