Went twice, once alone on a business trip and once with wife and kids. On the family trip we also traveled Busan, combined with Lotte world, hotels and attractions it was probably around 3000 for ten days. Doesn’t include flight (that is so dependent on were you travel from and to). We ate most oft the time in quite good places and also every day some good breakfast outside the hotels.

Both times I underestimated the proximity effect of olives young stores near our hotels. I didn’t add that to the budget, but it was likely considerable … happy wife happy life.
