Word of warning.
Whilst it is easy for mates to sit around in a pub and say they all fancy going away, a lot can happen between now and March 2014 (over a year away).
They can lose their job, get a steady girlfriend, get engaged or even married, move away from the area, change their mind and so on.
So it is VERY risky for anyone to book up flight or holidays on their own credit card or whatever unless EVERYONE has paid up front BEFORE the holiday is booked.
There is a very real risk the you (or someone else) will book the holiday and then one by one they will drop out and you will be left paying the bill.
You have been warned.
