If only 1 person is going to town, just catch a red-plate taxi on the beach road and ask to be dropped off 'plaza side' in town. They will pull into value master parking lot. Do your shopping / business, and then catch a beach taxi either from the Cambio parking lot next to value master, or walk over the bridge toward the beach, and catch a taxi to WS as you are on the downslope of the bridge. The taxis will be $100J each way, per person.

If all 3 of you are going in to town, then your best bet is probably a chartered ride, but i am not sure what to advise on price, which will include some waiting time. I would think $25-20 US?
