Kids/no kids

Is it acceptable to do a no child ceremony but to allow children at reception? Limited to 70 day and 110 evening (except for immediate family)

I have a child which means I know a lot of parents with children, although people are all over the UK, as our wedding will be on the coast it’ll be 4-5 hours travel for some, i don’t want to inconvenience people but at the same time, I can’t factor in everyone’s kids with a limit of 70.

We’re at a hotel so there is accommodation on site and a lot of local childcare options.
