Factual error: When Lucy and Charlotte are discussing the view from their rooms, Charlotte says they were to have South facing rooms with a view of the Arno and instead got North facing rooms without a view. Later when they have Rooms with a View - their view across the Arno faces North! The Duomo is on the north side of the Arno. (00:02:50 - 00:10:25)
Chosen answer: The joke is: The American girl asks her father "What did we see in Rome?" The man says "Rome was where we saw the yellow dog." Explanation: Americans can tour the Eternal City and all they will see that is memorable or of interest to them is a dog.

I don't get it. It doesn't make sense.
What part doesn't make sense? Rome is filled with better things than a dog. To put it another way, it would be like if you went to one of the greatest sporting event live with on-field/court-side/ring-side tickets and when asked about the event you said "I thought the nachos were good."

It's a crude joke about Americans. It doesn't have to make sense. It's a joke that highlights the sense that Americans are crude, illiterate, with no culture. They believe a yellow dog (a common dog in the US) was the best thing to see.
