Thx! What about general travel around San Juan with kids. Safe??
My wife and I (in our mid-20's) walked from that Hilton up to and around Old San Juan and never felt unsafe. The one area I was told to stay out of (especially at night) is "ghetto" looking area and cemetery north of Bulevar Del Valle between Fort San Cristóbal and Castillo de San Cristóbal (the other fort area) along the coast.
While I was occupied at my conference my wife and some of the other wives there went to one of the larger beaches and the big mall in San Juan had no problems.
If you do go to the rain forest stop at one of the food places on the way back down. Good food and cheap beer. The local beer Medalla is pretty good for a cheap light beer.
