San Blas, Nayarit, Mexico - Costs:

You don't have to be rich to vacation down here.  You can rent a bungalow for $200 or $300 US dollars a month (or less) and that includes hot water and a kitchen with refrigerator and stove.  If you rent by the day or week, it's quite a bit more.  Many of the bungalows are a bit run down with peeling paint and whatever but they do have their charms.  Most bungalows are in town, about a half mile from the beach.  If you are really on a tight budget, you can camp at the beach at one of the ramadas but it's pretty buggy.

Restaurants dinners for tourists run about $5 to $10 US, but there are some Mexico style places where you can eat for under $5.  Or you can stock up at the market and cook at home.  People say you can live on $400 a month but I spend about $700. 

The buses in Mexico are great but not cheap - fares to Tepic are $5 one way, Vallarta $10, and Guadalajara $20.
