We have tried to sign up for "No Queuing Advance E-Tickets" as described on Giverny.org. The hitch is that when we try to do it and have to use Digitick, we can't get them to accept our credit card. (We checked; we have pleny of credit available and have used the same card to book a multitude of other tickets.) We think part of the problem may be related to the required "mobile phone number." We live in California, and we have tried various combinations, including what we think are the correct international codes. We also tried just a straight local number, e.g. 6501234567 (650 being our area code). I could not find the answer or the format on the web site.
Got any idea? If so, I'd love your help.
By the way, our "Plan B" is to see if we can buy those tickets at Tourist Information at Gare du Nord when we arrive there.
Thanks in advance.
