I will say that my daughter’s friend’s family did this: they took a year off as a family and traveled around the world. Sounds very fun and apparently it was - for maybe a month. After that, the friend was tired from all the travel and constant instability - she just wanted to be back in school with her friends and on a normal, predictable schedule. I’m sure she did gain a lot through the experience, but I also know that she didn’t really enjoy it and after about month really just wanted to go back to normal.
So that’s also something to consider. What sounds great as a fantasy isn’t always so desirable as a reality.
