I sought the most expeditious passage, (KISS principal,) which turned out to be one of the least expensive overall from the US. While ground traveling, via train/bus to Pamplona, from Madrid, would have been exciting, it would have made for several transfers. Also, there was no additional cost for the Madrid to Pamplona leg. As it is set, I only have to ensure travel from Pamplona to SJPdP, with the worst case scenario being a 100 euro solo taxi fare to the beginning point. While it is too early to arrange for it, I will be trying to set up a date with the Corazon Puro pension folks, as they will pick me up at the train/bus station. feed both dinner and breakfast, provide a suitable bed and deliver this pilgrim to the starting point...all for about 50 euros...pretty neat. The other clear option is the bus, direct. Will be getting serious, about this minor gap, sometime after the first of the new year. BTW: Leaving NOLA on the 25th of April, via American Airlines, arranged through Travelocity.
