I call this, "Jackie Spratt and, Um, Jill Spratt."

I don't know (nor would I care to wager) that they are anything other than friends and/or relations. They might have even been total strangers waiting for their kids. The title is not meant to imply a spousal relationship. I just thought it was funny.
Incidentally I don't recall that Jack Spratt's wife had a name. In the nursery rhyme tradition I have called her Jill. I also considered Jane. Incidentally incidentally, you can't read it at this resolution, but the sign reads, under the "Notice" section:
Due to the design of the seating safety device on this ride, exceptionally large people may not be able to ride.
I think Jill is dead out of luck. Sorry, Jill.
