New year travel tips?

Following on from my last post I was just wondering how busy traveling in Korea is during New year and how difficult it may or may not be securing accommodation?

I will arrive Inchon airport Sunday 29th December and take the bus down to Busan. I only have 5 nights and have already been to Seoul before so was considering 2 nights in Busan, 1 night in Gyeongju and then I am open to suggestions.

I don't want to travel to far and wide as I don't have the time so would prefer to stay around Busan and Gyeongju.

Any advice on hostels, other places close by and travel tips will be greatly appreciated.

Thanks :)
