weddings - no kids allowed

No one force it onto hosts to change any of their plans. Off course people have only 2 options (as you have already mentioned) but there is no harm discussing it how to make it better.

By the way sometimes even hosts miss out on something. like they might know that babysitting services can be obtained at minimum fee etc. There is no harm in tossing up the ideas.

I prefer Listen to everyone but do what you think is best and I believe many others believe on this too
