Hi there James,
Your Camino is not long away! I am not sure where Reus is, but you would actually be too late to get into the albergue at Roncesvalles anyhow, as the doors close are closed by 10pm. The night I was there the lovely Dutch hospitaleros started playing calming, relaxing classical music at 9.47pm, and the lighting was reduced. Soon after 10pm all was quiet. Then at 6am there was some classical music to wake up to, as the lights were all switched on.
Most of the cheaper albergues in Spain seem to have a curfew around 10pm where the doors are closed etc.
