I can agree with that

but it still doesn't address my comment IMO at least.
Most often you're going to find the parents inviting the kids not the kids inviting the parents--at that stage in life. Certainly there are trips here and there I mean my mom went with us to Vegas and my mother-in-law is about to go on a ski trip with us however what you're talking about is every trip. I'd hazard a guess it's not the norm for the kids to say "hey mom and dad wanna go on a trip?"
So why not say "hey parents why do
you want to travel with your kids rather than instill a sense of independence, etc?" Obviously it's your thread I just found the question more negative towards the young adults when I feel it's more probable the parents inviting the kids at that stage in life. Obviously young adults can say no though.
* ETA: Again your thread just me musing out loud here
