So I'm deciding between Bali or Korea for next year spring break 2025

So for the Bali trip, it's for a sociology class that would be for two weeks (March 13-March 30, 2025). We'll be living with a host family like we're the locals. For the most part, I'm told we'll be going to temples, do prayer rituals, help out with the local community, learn more about their economics (tourism). I'm also told they have restrictive diet mainly consisting of vegetables & fruits.

The total cost of this Bali trip is $2,000 (accommodations, meal plans, & main class activities will paid for within the $2,000 price). I would need to pay for the flight ticket by next month (Dec.) but they'll reimburse me. The class also gets a grant that will help pay for the trip too ($500 for undergrad & $1,000 for graduate), the remaining balance for trip should be paid in cash two weeks prior the Bali trip.

While Korea trip, it's just for fun. I will pay out of pocket for it of course and I was thinking of going with my sister. I was thinking of flight dates around March 17-March 22, 2025 since that's my spring break next semester. I was looking up on Jeju air and I had estimated around $323 or $343 sum round trip for one week in March (around those dates listed above earlier). I had friends who've been to Korea before told me that I can just live off the convenience stores for food since they're so cheap. I was told to check out their Airbnb too since they would be cheaper to stay at. And a lot of cool places to check out there too such as the Gyeongbokgung palace, starfield library, cool & unique cafes, etc.

I've never been to either Bail or Korea. However, my heart is torn on which place to go for next year spring break 2025. Please help me decide lol. For Bali trip, I have to use all of my next paycheck plus some of my savings while for Korea trip, I can pay the roundtrip now with half of my next paycheck & just save up some money for accommodations, food, etc. next year.
