Given a travel related situation, and given a specific question about the situation, summarize the question into a title
One example: The green carriage is of course first class. This would be our first preference with our 5 month old baby in lap, because of the presumably larger toilets for changing and whatnot. However, the baby being a Western white baby... will occasionally babble, screech or cry uncontrollably for a little while.

Speaking in terms of Japanese culture, should we avoid Green class tickets if we are taking aboard a potentially disruptive baby?

Solution is here: Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car?
Explanation: A person gives a detailed description about a situation where they would prefer to travel on the Shinkansen Green Car but is doubtful if doing that would be against the Japanese train etiquette since they will be traveling with a baby. The question is summarized as Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car? for easy indexing the next time someone searches for a similar phrase

Now, solve this: Upon visa-less immigration to Cost Rica, I would have to prove sufficient funds of $100 per month of residence (Source)

Since I don't expect them to have a dollar-giving ATM before immigration control at San Jose airport and my local currency is Euro, I wondered how I can prove that.

Euros are not accepted in Costa Rica I'd guess. Banks in my area could give me a $100 bill (but none of them could provide Colones yet), but does the next taxi driver have sufficient change to accept it? Or will immigration control accept any bank account report showing I have more than 100 Euro on it?
