Maybe the next Mega Do will be a Kilo Do, with travel on an E175. That will preserve the exclusivity of these events as their appeal becomes more selective.
Seriously, it's odd that the Mega Do is having trouble drawing attendees when FT University and similar events are overflowing. It's almost as if the community of interest is changing from road warriors to credit card churners.
Heck, make it a Cessna Caravan and get even more exclusive!
I don't know, at one time I had planned to eventually do one of the Mega Dos, but for whatever reason, I'm feeling turned off by it all now and just not interested. Not really sure why.
As for this one in particular? A lot of cash for a North American-only trip and the destinations aren't all that exciting to me anyway. Luggage factory? Meh. Personally, I can tour AMARC anytime I wanted to arrange it...even if I couldn't, I certainly wouldn't sign up for the MD just for that.
