How old do you have to be to travel to another country and to stay in a hotel?

I am 14 and planning to go to france via the Eurostar (I will be 15 then though) without any parents so I was wondering how old you have to be to travel with friends also of that age?



Also, how old do you have to be to stay in a hotel with friends of the same age?How old do you have to be to travel to another country and to stay in a hotel?most hotels wont allow you to stay unless your 18How old do you have to be to travel to another country and to stay in a hotel?Is ok as long as you pay, I'd say.



I went to Czech Republic with 3 friends when we were 16 and there was no problem at all with the room, only with the Bar service... ^^
