can anyone tell me how common is it to run into jelly fish? Are they right out in front of the resorts, or do you run into them more when snorkeling/diving? Can you tell me what is the best thing to do if we run into one? We are going in 20 days, I hear they become more prevalent in April and beyond, do we even need to worry about them in March? Thanks, any help much appreciated! Don't want to spend our vacation in pain!!
