I would expect it would be easier - so long as the SCs are near parks or playgrounds - kids get sick of being chained to the back seat for too long - get them out to run around every so often = happier kids = happier trip!
I haven't seen any indications online (e.g. Plugshare comments, etc.) that mention parks near superchargers. Also, with my kids (2 and 4 years old) any car ride over about 2.5 hours and they lose their minds. Stopping for 15 or 20 minutes and then making them get back in the car again would only make it worse. Much better to power through and get to the destination ASAP.
I remember the last longer road trip of about 6.5 hours we took with my daughter when she was two years old. I am pretty sure she screamed for 3 of those hours. Lots of fun.
