I think a small wedding can be nicer, than something that looks like a 'stage performance'!
People everywhere is not fun.Plus it is a lot of money, and that can be better spent, on a honeymoon. 25-40 people is nice.
Everyone is then better looked after, and it's still intimate.
Some people really go well overboard, and the wedding can then look 'tacky'.
Good taste fly's out the window with some weddings, and it is just a circus.
