Good luck @(you need an account to see links) you'll do great!! University's an exciting time for sure
Actually Vietnam's really cheap! The flight there is expensive but living there is sooo cheap. We stayed at really nice hotels for like 30 CAD/ night, and we had meals for like 1 or 2 bucks, cause of currency exchange. It was tropical and beautiful and there was so much fresh fruit everywhere. Like mangos the size of cantaloupes.
It was our first time in vietnam too but definitely consider it for your next trip!!
