I am on the Francis now. Arrived from Primativo to Melide yesterday and walked on to Boente for the night. Got to the Albergue at about just before two and by one hour after that it was full. Today I left the Albergue in Boente in the dark - first time I did that since starting my Camino in Vezelay - I left because the Albergue was so crowded and I spent the night next to a major snorer, so didn't sleep. Glad I did as I got to Pedrouzo just before 1pm so got a bed. It is now 3.30pm and all places in town are full. The walk today was HORRIBLE. One long line of people all the way. Most with tiny backpacks or no pack at all so most doing 'day walks'. Worst walk of my life. I notice the paths have been widened since I did the Francis in 2013 - to accommodate the cyclists maybe who race past and have no bell? I nearly got bowled twice. Or, the track is always so crowded. Great pity.
My advice would be walk short distance so you get to an Albergue early, stop before or after the Breiley guide-book stops, or leave very early - yes it is a crazy bed race. Or, as some Primativo walkers did, get a taxi to Santiago from Melide ( they had already done the Francis). I plan to leave early tomorrow to try and beat the crowds. Goodness knows what Santiago will be like. A sad finish for me after a wonderful walk through France, the Norte and Primativo.
Good luck but be prepared.
