im 16 and the 2 girls are 18 and 27. i have permission from my parents just wondering if i will need any kind of permission to bring to the airport etc.
You will probably need your parents to be present when you book if you're doing it through a travel agent, or they may need to sign a consent form. I'm not sure how it will work if you book online, sorry.
Once your booking has been accepted then you shouldn't need any further proof of parental consent.
Just pop into a local travel agent, they'll have up to date info for you. You'll have the time of your life, I wish I was your age again! x
In terms of booking, as the others suggested, you might need parents present. However, the fact that a 27yr old is travelling with you, I don't anticipate you would have problems at the airport.
I know someone who recently took a 16 year old (not theirs) to Portugal - they were stopped at the border and refused entry, because they didn't have a signed permission from parents. I also know another person 17 years old who was refused entry into Gibraltar because of the same reason. So I would definitely check
