South Korea 6 Nights 7 Days Girls' Trip: "Schedule and Expenses Revealed"

I went on a trip to South Korea during Golden Week and here’s the schedule and approximate expenses.
I managed to get the flight tickets during a sale, so I believe I got the best deal possible.
We also kept accommodation costs under 4,000 yen per person per night, while enjoying good meals throughout the trip.
We took two day trips to regional areas as well. ♪
