Hi, I am bicycling the last 200Km of the Camino starting at Ponferrada. We will be riding 4 days and 3 nights. I am wondering about shipping my luggage from the starting point (Ponferrada/Saturday) to the end point (Santiago/Tuesday). The post offices are closed on Sat and Sun, so I was thinking instead of shipping from Ponferrada, I need to ship from Madrid the day prior to our start, which will then be on a Friday when correos are open. I am concerned about my luggage arriving by July 4 into Santiago if we only drop it off on Friday afternoon in Madrid. The correo website says they guarantee they will "ship" it within 72 hours. Since the post offices are closed on the weekends, a statement of "72 hours to ship" could mean the luggage may not arrive on time - 72 hours from Friday afternoon may be interpreted as they could ship from Madrid as late as July 5 (72 working hours later). Two questions to the forum: 1) I am wondering if I am misinterpreting how the correos ship and 2) is there an alternate shipping method given it is such a short trip and over a weekend?
