Traveling via bus and will stop at Alcobaça for a few hours before overnighting at Batalha and then the next day stopping at Fátima on the way to Tomar. Googled the towns' names plus luggage. Someone suggested luggage (just a carry on in my case) can be stored at the Fátima bus station but no info on Alcobaça. If the Alcobaça bus station does not have such facility, will it be possible to ask (nicely) at the local TI for help? Or, local café (hotel) for paid assistance?
For Alcobaҫa you can email: [email protected] and ask. There isn’t anything on their website about left luggage though. For Fátima: https://www.fatima.pt/en/pages/contacts.
