We will have a 3 month old infant (probably strapped in the Baby Bjorn the whole time) with us dining at Ohana.

Do I have to include the 3 month old when making ADR's? If so, why is that? Is it because they figure you might use a seat for a high chair or for an infant carrier?

What happens if you accidentally book the ADR for the wrong amount of people? Do they turn you away? I've never had that happen before, but we are usually just 2 people so its not too hard to mess up
