Only one, and that should be my best friend :)

Totally agree with deep_blue. With my best friend, or maybe my girlfriend (maybe she is my best friend) :)

it's better to take a paramour )

i think the best is four people , not too many because it will become more difficult to manage, women or men depends on the destination(i mean if i want to go to las vegas are better 4 men). but to achieve the complete freedom you have to be able to travel alone, there are many people that travel alone

it depends :) but I prefer many friends cuz it will be more enjoyable .
