Did everyone go on summer vacation?

Since the weather was so hot, I decided to go a bit later and took a vacation for next week.

I haven't decided where to go yet... I'm planning a domestic trip for about 2 nights and 3 days, but I'm not sure where there would be a lot to do..........

I'm looking into Sokcho, Incheon, Gapyeong, and Busan, but it's really difficult.
