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

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

New input: I will be travelling to Hong Kong in a few months' time. I hold dual nationality and neither of my nationalities requires a visa to enter Hong Kong. During my trip, I will travel to Korea for a few days, before returning to Hong Kong to fly home.

Will I require a visa as I will have multiple entries within 3 months of first arriving in Hong Kong, or does visa-free entry allow me to come and go (as a tourist), effectively, as I please?

I'm guessing that using my two passports would be something they would spot instantly and lead to further questions?

Solution:
Hong Kong: Visa for Multiple Entries?
