The Rosarito Beach Hotel is nice to wander around in, but attracts a much older crowd than Al, I think. Just a few hundred yards north is the Festival Plaza Hotel which attracts a mid-20s crowd and is definitely happening. For the best tacos in Baja, across the street from the Festival Plaza is a taco stand called El Paisano...simnply amazing and I've never had a bad experience. And at 50 cents a taco, it's a great deal.
