Hi, just hoping for some mood music/ general pointers really. We're planning a family trip to South Korea for my brother and his wife's belated Korean wedding party (he and SIL got married in the UK last year). DH and will be travelling over with DD (3) and DS (will be 6 months) in June, with DB, SIL and my parents. Am really, really excited. DH and I backpacked round SE Asia as twentysomethings and went to Bali for our honeymoon but haven't been back to Asia since 2009 and have never travelled to Korea.
The flight doesn't scare me, we've done long haul already with the kids and survived.
The itinerary is 4 nights in Seoul, fly on to 2 nights on Jeju, ferry over for 9 nights in Busan (where the wedding party is), bullet train back to Seoul and fly home.
Initial questions are around practicalities for the kids - what to do, see and eat, any outstanding places to stay - and in Korean culture, where do babies sleep? Cots seem not to exist. We're happy sleeping on traditional mattresses and sure DD will cope too but what about the baby? How do you stop them simply crawling away in the night/ stop dust/bugs/ravening wolves getting at them!?
Also - will people find it idiotic charming and delightful if I dress the kids up in Hanbok for the wedding party? Or dress up myself? My mother thinks it's a wonderful idea, I'm not so sure. Dad and DH have already said they will be wearing suits 
Any advice very much appreciated. Thanks in advance!
