Yep, 45 is the minimum to cover costs. We can cancel 2 months out with no charge if we don't have enough. That's why Pete is asking for payment by the end of this month, just so that we know without a doubt that it can happen.
Full refunds will happen if we have to cancel. There were 66 EOI at the start & more have come on board since then, so I know there are enough people who want to come, they just need to confirm with their $$.
