Here is the answer from the guide who led this tour.
I am sorry to read your review. I understand you got a bitter disappointment of Seoraksan Mt. tour in that bad weather day.
Especially, so much foggy and cloudy in the Gwon- guem-seoung fortress. This terrible weather could not let you enjoy the scenery. Basically, Seoraksan mt. is proud of beautiful scenery and landscape. That's why many people canceled the tours when it rains. Before the cable car, I told you there are many trails for walking. but you worried about kids could be more slippery...
About Lunch, I introduced the Bibimbap restaurants at the Seoraksan first. You chose the restaurants at the coastal area. I informed you may be need to pay some extra money over the budget in advance.
I thought you were very happy at the grilled fish restaurant. Because your family enjoyed every single grilled fish..
It seemed that there was some misunderstanding. I hope to see you again in the future. When it's comes, let me serve you with more attentive caring. Good luck..!!
