Visiting Korea with a number of people!? WOW~~~!!
First where are you guys from?
I really don't think you guys would have any problem with clothes.
Just wear clothes as you like...
But if you have a business meeting or something very important meeting, it's important to wear a suit first time. Other than that, wearing casual clothes is fine for adults and kids.
One thing you must be aware of though...
Korea is pertty hot and very humid, very humid!!!
As long as you are aware of that, your group will have no problem visiting Korea.
So.. you guys are visiting Seoul and Muju?
Muju for sightseeing?
I don't want you to re-schedule but, I really do have a recommendation for your group; especially for kids. When kids having fun, family are also having fun, right?
I know a place that kids will fall in love with. You guys too.
The name of place is 애버랜드 - 캐리비안 베이. Everland - Caribbean Bay.
For further info, take a look at
www.everland.com/caribbean.
Kids will love this place; even I do love that place.
I hope I did help you some.
Have a good time in Korea!
best,
Tim
