Wish I could help with this Tina - but being in the UK it's a bit difficult!!
I don't know whats around you - how about nature trails and lakes - anything like that around you. Most kids adore going on picnics - yes even to the local park or down to a river.
Even just doing things they've never done - or don't get to do a lot - e.g. a train ride. Little things often mean a lot.
Good Luck I hope you come up with something and have a lovely break.
