What's the fun in that. You're supposed to walk, head down, through the parks and stop suddenly about every 40-60 feet. Then yell at anyone that "rear ends" you.
"Watch where you're going! Idiot!!"
I kind of like the "pushing-a-stroller-with-head-down-buried-in-phone" folks who provide plenty of entertainment as they part the seas ahead of them.
I'm probably not the best suited to answer the OP's question because, in general, I dislike cellphones and literally do not carry one unless there is an ACTUAL need to do so. We have one between us, so I do have the option.
They call me a dinosaur - but I LIKE being a dinosaur in this case, so I don't care.
That perspective in place, I do find it a bit of a shame when people are so mesmerized in whatever it is they're looking at in the palm of their hand that they miss the rest of what I will call the real world about them. Which I think is REALLY a shame when you're somewhere like Disney. We talk about this instance every so often....
We're grabbing lunch at the Fountain in the Dolphin. There are tables along the floor, with high tops overlooking them. This family sits at the high top "above" us; I think it was three kids, mom and dad, with mom directly above me.
Mom's focus was her phone. Never spoke to dad or the kids through the lunch - just buried in her phone. I wanted to say, "do you hate your family, or are you just sick of them?". To me, part of the enjoyment of the deal is "sharing" any experience at Disney with my family, particularly the kids/grand kid. Even if that's "only" a lunch.
But that's just me.
Bottom line - if people want to play with their phones in line or wherever, that's up to them. It's not wrong - it's not right - it just "is". If that makes any sense.
Except for the guy I watched with the stroller plowing forward - - he needed to be arrested!
