i will have a 4yo and a 1yo when we go too we're also planning on 6days/7nights. although, im starting to think that might be too long. although hubby thinks it will be good because we can relax a couple days instead of just going non stop...kwim?
I think I responded to this same question on another thread...but the LONGER the better with young kids. Leaves plenty of time to go slow, schedule naps, and ride the MK rides over and over and over and over....you get the point!
