If the cost is within your budget. Take the train. So much nicer than driving or flying.
Amsterdam to Paris. Paris is a must see, one of the most beautiful cities in the world, and a great place to go on a anniversary vacation. Then from Paris on the train and through the tunnel to London and then on to Hinkley.
Sounds like a great trip.
Oh, and while your in London...could you pop into the Arsenal shop for me.

Sorry.
