Honeymoon on a cruise with kids

For our honeymoon my partner and I both want to go on cruise. It has what we want. It’s a floating theme park and we both are loving it.

However my mom is saying it’s not a honeymoon because it has kids it’s just a vacation to her.

Just looking to see other input on this. Is kids running around not a honeymoon to you?

(Side note we do not have any kids)
