Limiting entries by price hikes is not a good idea because it potentially precludes many riders. Some of us have the capacity to either pay or fund-raise to a high degree and some don't but that should not exclude us.
Limiting entries to a fixed number based on the capacity of the infrastructure and the number of support personnel (volunteer or paid) is a valid proposition. It does not, for example, make sense to try to send 10 thousand riders one way on the ferries and still expect them to complete the circuit in 12 hours. Limits should be placed on numbers based on the capacity of the selected ride option.
From what I heard from my colleagues who rode this year and last, the ferries from Queenscliff worked much better this year. This does show that BV can listen and learn. If there are problems, we need to continue to feed this information back with constructive comment.
The proposal for a professional event management organisation to run ATB is a possibility but I wonder whether they'd be able to do it for the same price. All the entry fees currently go to BV and I'm told that they really only cover the costs although I haven't seen any financials. If that's really accurate, then a contracted organiser would almost certainly raise the costs unacceptably.
