My FH and I have talked about having an adult only reception for several reasons. One being that we want to have a great time with family and friends, not having to worry about tantrums or screaming (like what happened at my aunt's 90th birthday party) or things spilling due to kids being out-of-control and so on. Second issue is that we are having a tent reception. It only holds 150 people and we would rather invite more friends and family instead of children that won't remember or appreciate going, especially since it is the same price.
The problem being is that we are getting married about 4 hours away and people will have to travel for the weekend. I know some people will bring their children because they don't have a sitter or want to vacation with them. I spoke with my MOH who's sister nanny's for work. I thought about hiring her for the wedding and renting a room for the kids to hang out in. Thoughts? Also, what should the age cut off be?
