I've seen a few posts on here recently asking if they should study abroad, is it financially responsible, etc., so I thought I'd share my opinion as someone who is very careful about saving and being (at least trying to be) financially responsible.
First, I'll admit, with the exception of a bit of traveling I did after my study abroad and the flight to get there, the costs were the same as my normal tuition, so I didn't have a huge increase in tuition to study abroad. Anyway, here are my thoughts on the subject as a 30 year old who studied abroad in Rome when I was 20 (sort of depressing it has been 10 years https://www.55printing.com/news/printing-and-mailing-holiday-cards-online/ ).
Studying abroad is a truly once and a lifetime experience. You get to live in a country for months. This is incredibly different than taking a vacation. When you are on vacation for a week you cram everything in. When you are living there you can wander the streets, go to attractions more than once, get a feel for how the people there really live. I can't recommend it enough, even if it might be hard financially, try to make it work IMO.
