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

Input: Consider Input: I will be arriving in Barcelona on the 13th of September and I will be staying together with my girlfriend for 6 nights.

Although I have a job, as students the budget is, let's say, a little limited. The hotel and the flight were already pretty expensive, so we would like to know if there are some places where we could eat a good lunch at an affordable price (10 euros, let's say).

First we will stay in El Guinardo neighborhood, and afterwards in La Vall D'Hebron. Nevertheless, the recommended places to eat can also be in nearby neighborhoods of the previously-mentioned ones or somewhere as "downtown" as possible.

If you think I can easily find affordable places to eat by just exploring the city, that also works for me.

I hope I don't sound cheap.

Output: First time in Barcelona: affordable places to eat for a student

Input: Consider Input: Searching for flights from Aruba to Ottawa, Canada using Expedia.com I run into this gem:

Is this doable?

Also, I read somewhere you could do US Immigration in Aruba, is this correct? (This would definitely simplify the process in Newark if it were so)

The flight would be the 20th if November, does this date coincide with high season or something in the US?

Output: 47 minute layover at Newark, is this doable?

Input: Consider Input: I am a US Permanent Resident(Green Card). I booked a ticket from China to USA. The flight is operated by Air Canada. It will have connecting flight wait time 11 hours 20 minutes in Vancouver.
My question is that since the connecting flight wait time is so long, can I take a tour in Vancouver, I don't want to sit inside the airport, Is that possible?
Output: Connecting flight wait time 11 hours 20 minutes - is it possible to exit to see Vancouver?
