I prefere travel alone or with my friends rather than travel with my family. I stopped traveling with them 3 years ago when I went with my friends to Malta for holidays. My family travel always with camper and I don't love it a lot. Moreover my brother hates the sea and he just wants to go in mountain, so my family go always there. I love mountain but the sea is the best for a holiday. I'm not going with my family for a lot. In my last travels I always went with my friend, in 3 or 4 guys. For example I went to Milan in october and even my family went there but two weeks later with camper.
In conclusion I think that I have different interests from my family, they like things that I don't want to do, but in particular they often go in the same place.
