We tend to charge our standard wedding fee and as they tend to be in our locality we don't hike expenses or expect a rider. They are very fruitful as they do tend to generate a good number bookings for the coming spring/summer wedding season so its a double whammy.
We all have kids so we don't go out at Christmas unless its silly money and 100% agreed, if anyone is reluctant it doesn't happen, no hassle. NYE is reliant on inflated fee and a big fat alcohol rider, an understanding that the band will be partying is also mandatory. I can't remember the last year I didn't 'work' so it appears to be an acceptable modus operandi.
