Alas their cancellation policy is huge and airtight - no refunds! Maybe you ask the Conceirge at the hotel you were going to stay if they can sell them for you to guests staying at that time! Good luck.

I'd go for Uber or ask your hotel to arrange taxi ,hope this helps from Neil K

Good afternoon! The Jardins de Claude Moneyt in Giverny are at least an hour away by car. I have never been but my husband and daughter dud while she studied in Paris and they said that it was amazing. Since you are on a cruise, a safer bet eould be to go to L’Orangerie museum in Paris. Many Claude Monet waterlillies murals there. You would also be able to go to the Eiffel tower. Hope this helps!

Shouldn’t be a problem, there’s a singer on first and a lot of people arrived during that time, you should be fine. We were advised to get there an hour earlier but would only have missed the singers, which were very good. Hope this helps

Non, tu ne peux pas porter sneakers. Tu dois porter les chaussures fancy. Have Fun! :)

They don’t ask for proof of identity so I’m not sure if it makes any difference?

Same! Since you are just changing the date, I would contact them directly! They were very helpful with us when my son decided to join us and they added a ticket for him at our table. Good lycj!
