Town draws day-trippers, others opt for local B&B April 19, 2002 Share 1 -- SAN SEBASTIAN, Mexico -- A dozen or so tourists find their way to this mountain town every day or so, depending on the time of year. They arrive by four-wheel-drive vehicle, having survived the journey up the twisting road from Puerto Vallarta. Others fly in from Puerto Vallarta on tours arranged by Vallarta Adventure.Buses depart Puerto Vallarta each day for La Estancia, a mountain town an hour from San Sebastian.It also is possible to flag down a ride to San Sebastian or pay a local driver to complete the trip.Some, like my group, stay only for the day. Others are fortunate to have a couple of days to explore.With that target group in mind, a Welsh couple named Mike and Pauline Hussey opened San Sebastian Bed & Breakfast last November. Bookings are commissionable at 10%.The Husseys had vacationed in San Sebastian for years before they were permitted by the town elders to lease a one-story hacienda near the church and open their business."We have two rooms now and will open more by next winter," Pauline Hussey said. "More than 90% of our business so far has come from the U.S."Their first season, which ran from Dec. 1 through March, "was pretty good. We were occupied at least four nights a week," she said.Mike Hussey runs day tours from San Sebastian for his visitors, taking them on hikes and drives in the mountains.Rates, which include twin-bed accommodations, a private bath and a full breakfast, start at $90 per night, double.For information on additional Vallarta Adventure programs, go to www.vallarta-adventures.com or firstname.lastname@example.org.To make reservations, e-mail email@example.com. -- G.N.M.
