I will be leaving to go to Cancun in less than 3 weeks, and was wondering if there has been any sea lice reported this season. I have read they they can be pretty nasty. On my last trip we didn't have the slightest problem with them, and hopefully that will be the case again this year. Also, does the Wal-Mart in Cancun sell the cream that prevents you from having a problem, and if so does it work? Thanks for the help!
