From my experience it goes in cycles, our three kids when young loved the touring caravan and then our replacement static van by Lough Erne. They then went through a period of not wanting to go to it, that was until their own kids came along then their interest was fired up again.
Now we have the Arapaho and set up camp for months in Spain they fight to schedule their visits to us with our grandkids.
So be prepared for rekindled interest in joining you and enjoying it again, you might need an extension, we use a tent for the overflow.
