Ok - the bottom line on Sting Ray Tours? I've decided to venture out and book a private tour instead of going with carnival. We dock at 7:00 or so is the plan. Is it ok to book the 9:45 tour? Soto, Bryan or Marvin - which to do? Any advise would help. I don't want to leave this trip up to chance. And....I'd like my money back if we don't make it there. I know Soto you pay when you go, are the others like that?
