The more usual scenario would be to get a boat and sail somewhere/around the world. You'll find several accounts in that vein.
I've seen a few stories of families on an extended bike tour. But not that many.
And let's not forget the RV expedition.
I don't remember *ever* reading a regret story.
Have fun with your plans
[edit]
We travel quite extensively (sail/bike/hike) with out kids. Summers, though. A sailboat is the best and the worst option. Bike touring is great, but might be a challenge if year round.
