question:
Soon, my wife and I want to travel from Faro to Lisbon by train and back a few days later.  I have found this website: Comboios De Portugal.

A complication is that we are not exactly sure when we will get to Faro.  So, if we book ahead then we will need to play safe and book a fairly late train.  Alternatively, we could just turn up at the station and buy on the spot.  My experience with UK trains is that this is a poor strategy as the prices will be bad and we might not even get seats.  So, here is the question: which of these strategies?


Book ahead as the prices will be better and we will certainly get seats.  Accept that we may need to hang around in Faro for a few hours.  
Just turn up at the station.  The prices will be the same or similar and there will be little danger of no seats.  
Something else that I have missed.  


The prices on the website seem reasonable and first class is not much more so we will probably go first class.  

Update.  I am on the train now.  It was at the platform 30 minutes before departure and it departed exactly on time.  Despite the booking site showing that it was nearly full, it is in fact almost empty.  I guess that more may get on at intermediate stops.  The carriage is nice: roomy, clean, and comfortable.  Storage for large bags is not great.  If it was actually full then it might have been a problem.  However, it is at least as good as trains in the UK.  

One minute late out of Loule and a few people got on.

7 minutes late out of Tunes and it is close to full now.

Final update after quite a few trips.  Ticket buying is easy online for major routes and you do not need to print the tickets.  You will be asked for an ID number, e.g. passport, but we never had this checked.  Local trains may require old style paper tickets bought at the station. It is a good idea to book several days ahead in a busy season as the trains often sell out.  Punctuality is erratic. It seemed good at first with delays of at most 10 minutes but later we had some trains 30 or 40 minutes behind schedule.

Buying train tickets in Portugal


question:
I'm 15 days into a 30-day trip all across Greece (Athens, northern mainland, islands). Everything has been great except the long wait each time we are ready to pay our bill when we're out to eat or for drinks. In America, cleared plates or a credit card/cash sitting on the table is an indication that we are ready to leave. Here it seems they are in no rush at all. We've even waited 20 minutes (they weren't busy). They print the tickets and bring them out immediately but take much longer to take payment. Multiple times we've had to walk to them - which feels a bit rude.

My question
How do I more clearly indicate that I am ready to pay and leave?
or
Am I just being an impatient American not attuned to the Mediterranean pace of life?

answer:
How do I convey that I'm ready to pay my tab in Greece?


question:
I had my ESTA approved last year when I didn't have a job hence put NO under DO YOU HAVE A CURRENT OR PREVIOUS EMPLOYER?. Since then I have both received and ended employment so if I were to apply for an ESTA now I should answer YES to DO YOU HAVE A CURRENT OR PREVIOUS EMPLOYER?

I plan to go to America and stay with some friends for around 2 months before returning home and looking for another job.  

When I tried to update the ESTA information I discovered that you may only make changes to information related to your Travel Information.  

Will I need to apply for a new ESTA that contains the correct information or will I be able to get by with this one and will the fact that I recently left my job or that I plan to be there for 2 months be an issue? 

answer:

Must I reapply for an ESTA following a change in employment status?
