Haven't been to Korea but I thought I would share some advice from my son who is spending a year abroad, studying in Japan. He said that he is often asked what he misses while there. He chooses to focus on what he HAS while he is there. He said he didn't go to Japan to experience what he had in the U.S. As a result he is enjoying his time immensely. He is enjoying new foods he never thought he would and he is trying to keep a blog on all of his adventures. He also loves to tell me about the funny things. The amazing thing is that he has never been an adventurous child so I am blown away at his maturity. He says it's because we moved so much and he had to learn to accept what reality was.
I would suggest you start a blog that all of you, even your kids, can add to. Add lots of photos as your friends and family will be so curious about what you are experiencing. And keep everything positive with your kids. Keep reminding them of the adventures you will get to experience and the surprises since none of you have been there. Tell them you will be keeping a blog of all of the adventures and surprises and that you will let them take pictures and write about the fun adventures. Don't let them ever hear about your fears. And if they mention that they have fears, tell them it is okay but you will all be there together and you will make an adventure of it. If they miss things while they are there, just keep reminding them of what they do have and what they get to experience that none of their friends get to have. And remind yourself not to dwell on what you won't have. Your kids will get to learn how to adjust to change and especially how to enjoy it! Have fun!
