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

Example input: 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 output: 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
Q: I hold a US Business visa (Indian citizen). I am travelling to the US from India and taking a layover in Italy for two days. So my travel plan is as follows:

New Delhi to Rome
Will stay in Rome for one day
Flying from Rome to Venice
Staying one more day in Venice
Flying from Venice to US (Seattle)

I can't apply for a Schengen visa due to shortage of time. I searched a little bit on "Italy Transit Visa" and got to know that there are three types of categories:

Transit Visa-A: or Airport Transit Visa: If your connecting flight to your destination is in the next couple of hours (not more than 12 hours / Not sure) from the same Airport. You might need to apply for such a visa (Some countries' citizens are obliged to stay in the airport area without having an Airport transit visa).
Transit Visa-B: Destined for the travellers planning to travel through different Schengen countries by car or travel through different Schengen airports to a non-Schengen country for as a final destination. Under the transit visa one is allowed to reside in a Schengen area for a maximum of 5 days.

Reference: Information about Schengen Visa

I also read that If you have a valid US visa then you don't need to take an Airport Transit Visa (Same if your citizenship comes into the following cities). Is it also valid for the B-Category as well?

My travel plans won't take more than 5 days. Am I applicable for Transit Visa-B. If yes, then can I apply for this visa on arrival in Italy?
