As a gift to my niece for her HS graduation, i am taking her and a friend to Cabo in the end of June. I own a time share at the Grand Solmar and Playa and have been there several times. My niece is 18, but her friend is only 17. I have read on other sites, that there may be issues with getting her into Mexico, because she is not traveling with her parents. Does anybody know of or have experienced any issue?
