Event Fee or Weekend Fee??

Okay, we need some input from the committee on this, but I am not sure that more than 3 of us are actually regularly reading this blog... We are working on budgeting and locations and have found that classes usually have either an event fee, where people pay per event they want to go to, or a weekend fee, which is what we had been highly considering, where you pay a flat rate and get into all functions. This appeals because it is easier for accounting, and also for checking in people at the door. If someone can't make a certain function, it just goes into the pot for the greater good of the weekend. So, let's hear it, what do you all think? And what do you think we should budget for per person. It seems that most reunions are in the range of $75-$100 pp with discounts if paid in advance. Do we all think this is a reasonable and fair charge? Maybe $75 if it is paid by Dec 31, $85 by March 31, and $100 after that? Perhaps this number can be lowered based on sponsorships, or would we prefer the sponshorships cover the extras and allow us to have a super nice event? Let's get some input because until we have a budget, we can't really make any venue decisions. Will post on those in a second.
