BTW, are there are rail services in Andalucia that don't accept the Eurailpass? I have one, but both the Eurailpass and Rick Steves' guide to European Rail Deals sites are down right now, so I can't check. If it helps, I have a Youth second-class two-month pass.
If you have a Eurailpass, you should be good.
If I go during Ramadan, which services will be shut down?
Nope - they still run as normal. Just remember not to eat or drink in front of any Muslim, except during the evenings and nights. Many communities have free public iftar meals that I would suggest going to, as you don't have to pay for anything.
Also, how goes the campaign in Puerto Rico to become a republic instead of recognizing the British queen as head of state? A Puerto Rican friend here in the United States of America supports a yes vote, so I wondered what your take on it would be.
Well, in that case, . . . .
This is when it gets funny. The Diaspora prefers a republic, whilst Puerto Ricans in Puèrto Rico, both anglophone and hispanophone and both those living in Borinquèn and the Virgin Islands, generally prefer retaining the links with the Crown due to, among other things, a history which goes way back (including the current British military presence). Pro-republic supporters are a minority here in Puèrto Rico and even then they haven't decided which form the republic should take (not to mention that they have suffered numerous setbacks and scandals and controversies) - and since Puerto Ricans living abroad don't have the right to vote, it makes things easier for us. It's basically a non-issue.
