We've booked tix for spring break 2005 to Paris. Kids are 11 and 13.

We're flying in Saturday morning, flying out Sunday morning. I'd like to spend 4 days in Paris, and then either take the train or rent a car and do an excursion, preferably to one destination (which could be a basis for car or other touring).

What suggestions does this group have? Would train to Amsterdam be a good idea?

Or is there a small city in the Loire Valley which would have its own attractions, plus be a good basis for touring there by car?
