Some people are not bothered, plenty of posters hate going away, hate staying with friends, hate travelling, want to stay home - perfectly normal too!
Absolutely this. I didn't leave the country till I was 18 (and then it was as an au pair), and had barely left my home county before that -- we had precisely two holidays during my childhood, both of them within 40 miles of home, both of them total disasters (tiny caravan, terrible weather, lack of research meaning that for some reason my parents randomly chose a B and B that was cheap because it was in the middle of nowhere and there was nothing to do at all except sit and look at the rain.) My parents hate breaking their routine, and have only ever left the country if we bought them flights to come and visit us where we were living, picked them up at the airport and made sure they didn't have to encounter any foreignness. 
However, DH and I made up for it by travelling a fair bit on the cheap in our student years, on work abroad visas, and as we studied at very international universities outside our home country, we have friends from all over, so holidays often involve house swaps or staying with people and that cuts costs. And as we had DS in another country, he took his first flight almost as soon as he got his first passport, at a few months old -- and in fact he'd been in France, Italy, Hungary, Spain, Switzerland and probably some others by the time he went to pre-school. (Most he has no memory of.)
I do take him out of school for a day or two at times to visit friends overseas on cheap flights.
