How often do they go now? How often will they go later on? Sports activities? Other? Personal opinion...I would buy what you would be comfortable with for several years. My cousin and DH bought with the grandkids in mind and they went maybe 2 - 3 times a year....the rest of the time, the bunks turned into a catch-all. When they sold it, they planned to get a model "for them, never mind the grandkids". Ended up they decided they'd not buy again. Consider, too, that as the GKs age, they think a tent of their own is a very cool thing and if you're comfortable with that, all the better.
