Wow! Can't believe Regent is charging that kind of money for a bus trip into London. Are you sure the car/van (not thru Regent) is $335/per, or is that for the car/van? Either way, I'm glad we took the post cruise at the Goring with private car and a tour. What seemed very expensive doesn't seem so any more. We're going to see Mamma Mia the evening of the 13th as well.
