We tend to just have a walk along the front and chat to all the boat trip people to see who can do us the best deal. I also think we've used someone in the past who is linked to the florida bar in some way. It's not usually me that sorts out the trip, i just pay the money.
When we go to
icmeler we go in big groups of about 18/20 people, we tend to pay between £8-£10 each to charter a boat for the day just for ourselves, that generally includes lunch too.
