Do you want your kids to grow up in hotels and short-term rentals, never having been in one place for too long? If the answer is "sure", talk to people who grew up in military families who were shipped all over the world -- it's not fun.
If the idea is that you're going to travel, and the family stays put, understand that the cost is that you won't have a family at some point. Road-warrior consultants generally aren't the happiest people.
So true, I did similar kind of "on-the-road" consultancy for a 9 month period in a previous role and that was enough. Saved a load of money though as I had no accommodation expenses of my own in those 9 months.
Here [1] is a family of 7 driving from Alaska to Argentina... because they want to.
I met many similar family expeditions during my drive [2] and it was always a joy to meet the kids - who were all bi or tri-lingual.
One of my favorite quotes from a ~10 year old was "I don't like homeschooling.. I like WORLDschooling".

* Where did you decide to live? * How do you support yourself and family? * What do you do for school, is it expensive? * How's it working out? Any regrets?
