We will be visiting the BI this coming January. Some friends are coming over for 3 days to join us and we have made plans to take the circle island helicopter tour and a guided snorkel tour of K bay as recommended by you both. Here's the problem, there were going to be 6 of us so we would have all fit in one helo and one zodiac but now another couple is joining us. One of them will have to purchase two tickets on the helicopter because of the weight issue and I don't think a zodiac will hold the 8 of us. Do you have any solutions or opinions for these two "touchy" issues. Is there another smaller scale snorkel tour that could take just the 8 of us? Is there a helicopter tour operator that will take 8 and are sensitive to the weight issue? Thanks for any help you might give on this. I'm the designated tour guide for these 3 days and am struggling with what to do.
