Thanks mate, good points made.Dave, I want to add few things or explain my thoughts about travelling in the group:
Since we are going to be NOT walking distance from anything slightly resembling the store, where Ivan can buy his BEER!!! we would need some kind of the transportation. That is First.
Second: regardless where you are going to fly ( Belize City or Cancun) everybody will need to take few buses (or as PaulW asked - possible local flights).it is possible, but busses are going with same regularity, although not as often as ones from Piccadilly to Buckingham, so it will take some doing to get there.
My idea was (based on the number of people in the group) rent on van, pack all of us in it and get the hell out of the airport to the camping grounds. The cost to rent the vehicle dividing by number people will be more affordable and more convenient. ( And Ivan could do his evening beer run driving instead of jogging 4-5 miles.)
This all required real organization, so we can wait until our group will be organized. Since I probably know no more then 5 minutes of material then everybody else - when time comes - I will try to take care of it.
Meantime let's see how the group will coalesce.
