Holiday Destination

I'm working on organizing a Korea trip after B1's exam. UOB Travel has a ski package that I'm quite keen on but it's going to be tough for lo Gung. The itinerary requires us to fly out at night and tour starts in the morning once we land. Out of the 5 nights, we need to change hotel 3 times, something he doesn't like. I'm checking if I can DIY a package so that even though we have to change hotels, it is at a more comfortable pace for him. I'm planning to fly out in the Day, stay at Seoul or a town for one or 2 nights then go to a ski resort for 2 or 3 nights (I'm planning Yongpyong), then spend a day or 2 at Seoul before flying home.
