We want to pre-purchase our tickets for the Orsay and Orangerie museums. I have read many of the posts here and find it confusing. I want to print our tickets at home, not run around Paris looking to pick them up. There are a number of different websites selling these tickets: digitick.com, fnac.com, ticketnet.fr. Which site do you recommend which allows the actual e-ticket to be printed at home? Thanks!
