Though I realize none of you is going to take my advice on this one, there is a strong argument for unplugging yourself from the Internet whilst on vacation and ignoring the very existence of such things as e-mail, Facebook status updates, and Twitter feeds while you're on the road.
Let your inbox fill up with spam. Let those anxious emails from co-workers and clients go unanswered. Heroically refrain from updating your Facebook status for days on end. Let the Twtter feed die and the blog roll come to a standstill. Just hang out a virtual shingle to the effect: "Gone Vacationin'. Back in 2 Weeks." Set up your email to bounce back an "out of office/on vacation" message and jack yourself out for the duration.
I'll use a budgetary excuse—postcards are still cheaper than 15 minutes on-line—but really I feel this is a philosophical issue. You're spending a big wad of cash to experience Europe, so don't waste some of that precious time (probably an hour tracking down, and then sitting in, an Internet cafe) keeping plugged into your life back home.
Your work can wait (you're on vacation, remember). Your friends? You can regale them with the tales when you return. Your family? Call them of Skype them as frequently as is appropriate for brief conversations.
True, the Internet is a fabulous tool for making the world a smaller place. But the whole point of travel is to discover how big and diverse the world truly is. Rarely does anyone have thrilling foreign adventures whilst sitting in the glow of a PC screen in a rented storefront. Get out there! Enjoy Italy!
OK, lecture over.
