I apparently am in the minority here but when my family and I are at Disney (or on any holiday) all electronics (excluding my camera) are left behind in the hotel safe. I check for text messages at the end of the day after the kids are in bed and I do not fb while on holidays.
As you can imagine life with 4 kids and a hubby who is only home on the week ends due to work is chaotic

so we use this time as a family to catch up, talk, I get to hold hands with my hubby

, I guess just be in the moment. All to quickly life passes us by.
I strongly encourage my kids to keep their eyes up and see and experience the world around them, that their experiences will be stored in their memory forever, not just on some
instagram account! So as hard as it can be (seriously how sad is that!) I try to live what I'm preaching at them!
But like in life, to each their own, just like others have said common courtesy and common sense can go along way!
