From reading on here I can see a few people are against them. I wouldn't probably go for one usually, but we have not long moved into a new area and we really don't know enough people yet for a decent sized party.
I was thinking of inviting the whole of his class of 30, the place I was going to hire is a set price no matter how many children, so it would just be extra for food.
Thing is i'm not sure now (tbh from reading threads on here!) that it is a good idea. Maybe I should just take him out for the day and have a small family party at home?
