shark.byte.usa:I was going to say that, glad somebody did Every boat, every dive, same hotel...What a nightmare!
That's really the difference isn't it? What really happens is you go solo and you end up trying to find a buddy on your way out to the dive site on a boat with a bunch of strangers. Maybe you hook up with somone that is halfway decent and stays with you through the week but that is pretty rare. All the dive op cares about is getting your money and getting you on the boat. After that it is all up to you. I personally don't have a problem with that but much prefer to dive with some folks that I at least have some minimal connection to.
As I said before..to each his/her own. This is all personal preference.
