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

Example solution: Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car?
Example 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

Problem: Next Thursday near 9 AM, I might have to take a cab from La Defense metro station to go to a district which is outside the subway zone.

According to this PDF file (in French) about Paris La Defense (page 4) and this map, there is a taxi station at La Defense not far from the metro station.

Google Street View shows the station, and there are five taxi cabs waiting, but there are only one cab from another point of view. The other lane is empty. This is scary.

Are there cabs available all the time there, or do I have to book a taxi before arriving at La Defense? If I have to book it, is it better to do it a few minutes before arriving, or should I do it the day before my trip?

After being at La Defense for five consecutive times near 9 AM and 9:30 AM, I confirm that there were always a lot of cabs available (always at least five, often more). I believe that this was also the case near 4 PM. Of course, the situation may be different on weekends.
Solution: Do I need to book a taxi before arriving at Paris La Defense?
