I also do vacation without internet access and without notebook. That's what vacation is for, isn't it? Vacation is for relaxation.
Internet only if really required for the trip (changing or booking a flight or emergency situations),
by using mobile phone internet (if available in the area

), or by using an internet cafe (if available in the area

).
Very good time, every year. I also do like minimalistic living, like camping in a tent in Australia's outback for 2 weeks,
or enjoying village life in Thailand, distant from Internet, Computers, and "modern civilization".
