Madrid in August is hot, hot, hot. We're talking two-showers-a-day hot. However, most pilgrims will be housed in group accommodation venues which means either a school gym, a community centre, or a parish hall.  All spaces can sleep a large group, but don't normally house young people for a full week. These accommodation venues have been outfitted with special portable showers that can be set up when pilgrims arrive and taken down after they leave. If you're staying in a group accommodation site there are a few things you'll want to know about the showers before you pack your rubber duck.
