Hopefully when you decided to have kids, you decided to make them the priority in your lives... Hopefully your desires won't skew your actions, or justify them falsely. Is it really important for a child to spend their life on the big travel adventure that their parents have always wanted to do? I'm not saying you're right or wrong. Just saying it's something to think about. Maybe they'll turn out to be the most amazing, cultured geniuses of our time. Or maybe they'll turn out weird, socially awkward, and unhappy because they never had a friend or even a chance to relate to anyone their own age.

Maybe just ask your kids and let them decide. And if they say yes, but one day decide they don't want to do that anymore, then stop. Once you have kids, they should come first in every life decision you make. Once you're a parent, you should no longer come first. If you decide to do this, it should be for them, not you. If it's not for them, you shouldn't do it.

If you're not looking for life, financial, or parenting advice, what are you asking about? That's all I've seen mentioned in your post. Bike or gear advice? You mentioned starting a discussion with others who have done this, but there are very few people who have. The very few who have aren't sitting around posting on bikeforums. In any case, if you didn't want advice on those things, no need to mention them... That's like starting a thread about your bike drive-train, mentioning that it has awful brakes, and then saying that you don't want advice on the brake problem. That's silly.
