Obviously the OP has no children (and my brothers' kids are grown up) - if you have kids this changes the equation completely (though if they're very young then it can still work).
It was not good.
I cannot stress enough how bad of an idea this is unless your children are under 3. Children need structure and permanency. They need friends, not just acquaintances. My cousin did everything else right, but his kids still have issues with relationships because 5 of their very formative years were spent without actual friends. It's really sad to think about.
For him, it was a wildly selfish move that negatively impacted his children. Don't be that guy.
This may be different to your situation, but when i was younger I wanted people to like me, and if they didn't I'd blame myself for being weird. Now I'm older, I don't give a shit if people like me or not, and I've stopped thinking of myself as weird.
obviously i don't know your cousin, but before you blame him, consider that there may have been other factors that you can't see, that were beyond their control.
the worst thing in my experience is relatives who think they know what i am doing wrong as a parent, without understanding the whole picture. (friends too, but once friends do that, they are no longer friends). try not to be that person.
Glad someone said it! I’m disinclined to take any parenting advice from a peer group that’s been raising kids on tablets for the last 10 years. But ya, moving around is the concern hah. God forbid they see life outside the suburbs.
There are more alternatives than the extreme you're describing.
AirBnB’s and homes are located in areas and designed for living like normal social human beings.
RVs are parked in areas that are not designed to sustain long term living.
In many cases they simply dont have any friends at all. Or are always the incomers.
Of course you can live in a place with lots of kids of your own age and still be lonly, or the kids can be dicks, but in my opinion there is benefit in socialization at age 4-10. Kids could go out ans play together. The nomads cant.
IMO permanent group of friends and place, repetition, predictability are a foundation for growth. Then you can sprinkle one off things on top. Not a life of unpredictable mess when you are on your own.
Also if you dont speak the local language how can one even socialize
We moved a lot as kids due to my dads jobs. It was nothing you can point at and call call crazy like living in a rv, just normal jobs like a million people have to deal with, yet has essentially the same effect as your nomad rv story. Some time in the air force followed by different electronics and computer engineering jobs that just resulted in a significant move every couple of years.
Depending on my mood I can say I didn't make a lot of friends or that I made exactly normal friends, and that any weirdness about me was caused by that, or was my own nature and that didn't change anything. I can think of argumants that sound reasonable both ways, and I can cite various facts (things about me, events and outcomes in my life, etc, and the same about others with different events and outcomes) that support both ways.
Which means what I choose to say or blame says more about me than anything else.
Every thing you can say about stability I can say something equal about conformity.
One thing I would point out is that military kids are in a far different scenario than the OP's cousins kids. Military kids will grow up moving from base to base, but the schools around bases are fundamentally different. Those are schools where teachers are used to student turnover, and the students are as well. OP talked about kids that were in a more nomadic situation, where they could only form brief <1mo friendships. The local culture of these communities is also used to and adapted somewhat to this.
That sounds like childhood trauma to me, the closest analog might not be military children but the foster care system. Not a 100% analog, since presumably the OP's cousins kids didn't have the pre-existing trauma that entry into that system necessitates, but that is the closest conventional analog I can think of. Moving around constantly into communities that aren't necessarily set up to deal with that is rough.
Our neighbors a few years back had spent years living on a boat with their child up until age 6, I think it was, and it was great. And their daughter had a very positive experience. But yeah, once she was older they moved onshore.
I don't think moving itself has a negative effect. If you stay long enough for your kids to establish friendships, sometimes those friendships can remain when you move. My 8 year old boy still plays almost daily online + FaceTime with his friend from 1st grade in another city even though they were only a year together they established a bond that is very strong years later and they haven't seen each other. They're still best friends.
The usual YMMV.
Also, it sounds like they were traveling for 5 years? Yeah, that does sound like a very long time - I imagine if it had been 1 year or so it might have been a very different story (?)
Same with the Adriatic. If you decide to stay in Dubrovnik or Split, for example, it'll be quite expensive, but there are other places to stay in Croatia that are non-touristy and inexpensive.
Also Portugal has the Digital Nomad visa for 1 year renewable. That requires employment in the US (or elsewhere outside the EU) so not the same as what my brother was doing but a good option as the min wage requirements are not high; could get by with what would be part time work on a US salary esp in tech.
I suspect that many of the housing problems in places like Lisbon’s old be solved if visas were enforced.
When I lived in Ireland I occasionally met people who would bounce between Ireland/UK and Schengen to reset their visa clocks (people from US, Canada, etc. can spend 3 months at a time, or 6 months a year, in Schengen, though eventually you might start getting tougher questions).

be careful about what you eat and drink but it’s not like you catch these diseases just from walking around.
