Sorry, Olivia - I wish we had known ahead of time, but it was a fun and interesting day nonetheless, just not in the style we are all accustomed to.

Check viator.com - we took a tour booked through them in Normandy and the operator and guide were really good. Also, check on cruise critic and TripAdvisor to see if anyone's talking about it and recommends any tour operators.

Keep in mind it was a pretty long drive from where the ship docked so that will be a cost factor. But if you figure the ballpark included Regent excursion is "valued" at $149 to us, then their cost is probably about half of that, so $100 pp probably isn't an unreasonable expectation.
