coupla thoughts... difference between a babe in arms, in a carrier and a little kids
patrolling/rampaging around. Don't think anyone is going to object to the former, but the latter? yeah well... kids
falling down companion ways, kids falling off decks, kids stuffing something into heads, kids spilling sticky stuff. kids sticky hands touching all that shiny pretty primped brightwork... annoyance at the least, liability at the worst.
Uh, yeah, given how inconsistent the parent population is, I might say no kids aboard too... The boats are often crowded with folks (who might be buyers) waiting patiently for the crowd to move on so they can have a look. Waiting because some parent can't be bothered to parent....
But I suspect the stroller, as others have said, is not a great idea. Maybe bring a little cable lock and lock the stroller up on the area before the entrance so you can have it before and after. Seems like there are always railings and poles around these things. Might be a big booth of a boat broker
who is showing down on the dock
who might allow you to chain up in a corner seeing as you will be looking at their boats... can't hurt ta ask ; -)
Depending on the crowds you *might* want it in the booth area, even if down by the boats is a bad idea.
