Our son left Friday for Bahia Principe Tulum. We asked him to call us when he arrived in resort. We gave him the same phone card we had used when we were at the Riu Tequilla a month ago and had no trouble using. As of yet we haven't heard from him. This morning we called our travel agent to see if she had heard of any trouble with the phone lines down there. She had 5 other parents call this morning wondering the same thing we were. She tryed to call the resort and other resorts near there and couldn't get threw at all. She didn't get a busy signal, just some strange noise. So we figure he is there , he just can't get a call threw. I was just wondering if anybody knows what is going on down there?
