Yep, I'd agree that 1 day is enough if it's not busy and you get there early enough.

Although in busy periods and taking into account ages of the children you're taking, 2 days could also work! Depends on whether you like rushing around or taking your time i guess.
If doing 2 days, the Premier Travel Inn is right next door, so very handy. Check around to see if there is a cinema in the area, that's what we usually do in the late afternoon/early evening time.
