Hi Kimberly, thank you for your review, and your points.
We ask the people if they can swim, so when they don't can swim we have a lifejacket or a snorkelvest for them. But for the people who can swim, they are free to choose if they want to wear a lifejacket. Where we kayak, 99% is less then a meter deep and there are no waves, besides that nobody ever fall in the water while kayaking. So the most people choose to not use a lifejacket.
We use 1 guide in front, but have 14 points in our route where we wait for everybody, most of the time the group will be very compact. If you feel uncomfortable, you can tell the guide and he will put you direct behind him.
About the snorkeling, we snorkel in nature, and yes you can be unlucky, that there are some micro organismes in the water that can sting. You can protect yourself against that when you wearing a UV shirt and trousers with long sleeves. Or a long snorkeling suit.
The spot that you mentioned for snorkeling next to the beach, I think for every snorkelspot, if you don't know, where to snorkel, and at what time, know the current, it could be a dangerous place. The place 50 meters from where we start. where the water is 50 centimer deep, can be full of hydroids (the thing that stings).
I think for the most points you mentioned, I think we have to communicate this better to the people. Like the water is almost everywhere less then 1 meter, but because it can be murky, you don't see it. Probably you feel more comfortable. Or that you can say, hee I don't feel comfortable as last kayak, so we can put you behind the guide. I can tell you because I did this tour with you, we do this tour already so long, without any problems, that we sometimes forget you don't know. I will take that with me in our meeting from the kayakguides
We will take some extra lifejackets with us. So we have more lifejackets besides the snorkelvests.
