You will be allowed to travel, and book into a hotel provided you can pay the bill...but please be aware that if this is your first time abroad without adults you will have to be very careful.
Resorts in these places are very popular with younger people and there are lots of unsavory characters waiting until you get very drunk ect to take advantage...i dont just mean sexually! Drinks are very cheap and are often different brands to what you get at home as well.
My friend was 17 and got chatting to a bunch of people by the beach, when she went to meet her friends she found they had stolen her passport and purse! (they were british tourists!)..magaluf
Another situation happened when a pair of teenage girls were stopped by a car with a flashing light and told to get in by 'police'...faliraki ..a local man came up and told the girls it wasnt a police car at all and not to get in.
On one trip to greece a woman in our hotel let her daughter and friend go out to the clubs, they separated from each other and came home alone in taxis...never do this! One of the girls had to jump out of the taxi becasue the driver was feeling her up! She was v lucky to get away.
Dont want to scare you, but keep your wits about you and you canstill have a good time (and come home in one piece!)
