My wife has a similar issue with the sun. No matter how much sunscreen she puts on she always seems to burn. Even when it is 60 spf. She just has really sensitive skin I guess. Her mom's side of the family is Swedish, and they always complain about their fair skin. This does look like a really beautiful place. My friends who just visited Mexico has similar stories about the umbrellas and cabanas getting snatched up early in the day.
Yep - my daughter is weirdly fairer than my wife! :D
Wife went and put towels down this morning - there was a massive line waiting and she got two places - but not "great" places.
Ah man, that's too bad. Plus you said this isn't even the busy season? I think that kind of stress would make it hard for me to relax.
