Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Input: Consider Input: I have a 10 year tourist visa for the US and have been back and forth to the US for some years now visiting my partners family, she is American by birth. 
We decided to get married after being together for 3 years. 

Our intention is to go to the US in the summer, get married and celebrate with her family, and then come back to my home country where we both currently live permanently. 

My question is, can we get married on the tourist visa if our intention is to return to our current country of residence?

I've had my own business for a long time here as well as other assets that can easily be proven to show that our intention is to return home, my partner has a job here and we stay together in an apartment that we rent and have a lease for, so lots of information to provide to the customs agent on arrival to show our intent is to marry and then leave to come back home. 

Furthermore, we might decide to apply for a green card for myself in a few years time, but for this trip we have no intention of getting married and staying in the US and applying. 

If anyone has some experience with this is would be greatly appreciated - thanks.

Input: Consider Input: As the UK is technically still a member of the EU, I just wanted to be sure of this before booking travel arrangements. 

The idea is to arrive in the UK and stay there for 2-4 weeks, and then afterwards relocate to and stay in mainland Europe for another 80-90 days. Is this possible? Or would I be effectively limited to 70 days in the EU after staying for example 20 days in the UK?


Output: If I arrive in the UK, and then head to mainland Europe, does my Schengen visa 90 day limit start when I arrived in the UK, or mainland Europe?


Input: Consider Input: 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.
