Thanks for that, but I would never encourage anyone to stand up at Hol Chan. I'm all about the coral.
And be that as it may, while there may be a few areas that she can stand up, there are more that she can't. I don't know how tall you are, but I can't stand up at Shark Ray Alley, but then I'm not the least bit uncomfortable with the whole thing.
My friend will be. She'll be scared about the snorkelling, just in its own right . . but once she sees the nurse sharks and the rays, she's really going to be scared. I'm admiring how she's keen to do it, even though she knows how she is when snorkelling.
