guys it looks like there are enough people interested in going so id say go.
organise a meeting (for the likely organisers of the trip) and get people (drivers especially) to commit to something, even if they only say that they will come along to the next meeting, it will give you a chance to convince them to come with you. then you need to get people who have experience over there to say they will go too.
you wont need freshers to turn up to the meeting and it dosent have to be too formal but have some sort of agreement betewwn you all.
IF YOU BUILD IT THEY WILL COME.
