My SIL and BIL are both there 🤔 I’m mid 20’s but they’re in their 30’s and one of his parents went with them!
I don’t think there’s an ‘age limit’ on doing something you enjoy but I do think there’s age appropriate behaviour! The pictures I have seen would suggest that they strongly disagree!
But then again everybody is different! You couldn’t pay DH and I to go and live like that for the weekend 🙄
