Hi. Neither my daughter or I had pre booked and we got in but I wouldn't say you could guarantee it.

I am not aware of any golf tour how can someone connect a golf tour with an art gallery?

My daughter took her backpack with our IPads. They searched it and she was allowed in., without any problem. There was one museum in Nogent sur Seine, they searched it, and required she lock up her backpack in one of their lockers. , That said, even they allowed entry. Of all the museums we personally went to in Paris, and surrounding areas, no one denied entry because of her backpack. This was in 2022. I suppose things could change, but, we had no problem then with her taking a backpack at the Musée d’Orsay. I love this museum!!!

Si. Io ho 2 figlie di 23 e 20 anni che sono entrate gratuitamente esibendo il documento di identità.

Ciao, avendo lo stesso problema potresti dirmi se sei andata e com'è andata a finire? Grazie

re-read the conditiions of your Paris Museum pass. It may well be tthat you can't reserve a time. HOwever, the use of your Museum pass is dependent on what you purchased. It becomes active with the first use. For example, I had a 3 day pass. But didn't start visiting museums until a few days into my stay and then the pass's 3 day time period began.

Mi dispiace, non ne ho idea.

Not sure about The Big Bus, but there was a special for D'Orsay and the Orangerie.

Non ci sono problemi, anche io per errore ho prenotato due biglietti entrambi a mio nome, ma non hanno posto difficoltà all'entrata. Guardano più che altro il codice a barre presente sul biglietto. Buon viaggio!
