Halloween wedding date - but groomsmen have kids

Hello again! I feel like I'm posting constantly in these forums. Anywho, to get to the heart of the matter, my ideal wedding date is friday 10/30/2020. For spiritual reasons (it's close to a spiritual holiday but not on it) and it's on a blue moon (so romantic! At least to my cheesy nature-loving butt). However, there's this venue I ADORE and it's part of the Massachusetts Audubon Society, but they only do weddings on Saturdays and Sundays. So to book this venue I'd have to change my date...to Halloween.

As much as I adore Halloween, I was trying to avoid having it conflict with my spiritual holiday annnnd make it so guests with kids don't have to choose between family traditions or me and my fiance. Two of his groomsmen have kids, one is a few months old at the time of this post, and the other groomsman's kids are I think 3 and 5. So they'd be about 4 and 6 I think. How do I handle this?


I know it sounds dumb but I really love this venue and really was hoping for an October wedding (October is my favorite month) if not one that has that moon...
