Great idea, and something I've already seen at malls and airports, but...
You're on vacation. You're already taking a break from the physical world back home. Shouldn't you also be taking a break from the online world? Nobody ever thinks to take vacations from that, and while it may seem strange that I'm writing this in an online forum, I feel the world online is the more stressful of the two sometimes.
When I take my next trip, I'll be leaving my cell phone at home. No texting, no calling me wherever, no social media, no email, not even Disboards. I know I won't have the convenience of the My Disney Experience app, but it will be so liberating to be rid of that thing for a week. I'll be taking a good Nikon camera to document the trip, but I'll be free of both worlds instead of just one.
