Sadly, since being robbed by a passing motorcyclist, I am much more wary these days. I also remember our driver once, who was changing a flat tyre, (out on the highway),asking me to stay in the car and watch valuables, he was worried someone by pull up and snatch from car.
If you are out on an organised boat/ car tour, I would feel comfortable with leaving possessions with guides.
But really, I think you run a risk in just about any other situation. There are totally waterproof money belts that you could put bike keys, mobile and room keys in when swimming. Available online or Outdoor/ travel or Dive shops.
