We are from the US. Thinking ahead for summer of 2023, we will have a 16 year old and an 8 year old. I feel like it would be the perfect time to take the 16 yo but too soon to take the 8 yo on a European sailing. We don't have much of an option of not taking the little one and I want to take the older one before she finishes high school. Is 8 or 9 too young? Are there any itineraries you would recommend for a younger child? Would you just wait until the younger one is older?
