Unfortunately we were too late in the game to book with Rick's recommended tours, but Normandy Sightseeing Tours has openings. Has anyone used this company? They are asking for a credit card via phone, fax, or mail and I'd like to know they are legit before sending my information. Fairly good write-ups on Tripadvisor.
With good write ups on TA, unless it is just two, I would trust them. Use email for your credit card number. That is the safest way to transmit information.
Thank you so much for the info - we will proceed!
