tom911,
Truth be told, a thank you is all I'm looking for. I couldn't charge enough money for all the time and effort I, and other Do organizers put into their function(s). This is a labor of love. It gives me great pleasure to host Flyertalkers when they come to the NY area.

All fees for the BRT, and this year the pre-paid WineDo, are calculated upfront. In past years, I reminded everyone that there may be a cash call if for some reason folks drop out. Getting pre-payment is key to not getting burnt. No organizer should be stuck for out-of-pocket expenses. I will admit to rounding up by a nickel for one event. Let's see, that's 50 x 5 cents.
Every year, Do organizers learn from past events. I had to pick up for a meal for our bus driver on the BRT. This year, I added a few cents (and that's all it is) to cover the cost of his lunch. FYI, for WineDo 3 (pre-paid due to a private room), the actual amount asked for was $79.68, or $82.37 if you used Paypal. Next year I'll round up.
I would say
no to an administrative fee.
