But I wonder how pre-registrations will really allow AHA to truly measure demand since I am assuming there is not a cash/payment commitment. One could simply pre-register and then flake...putting those on the wait list into a fury trying to get there. I tend to understand the move but the amount of work for staff to manage registration with pre reg and wait lists...seems excessive and unnecessary. I worry the pre reg process will actually greatly decrease the amount of attendees who actually attend since I don't lose anything by pre-registering. Curious to see how this works out. I hope I win the lottery! Ha.
