Impeccable timing for this thread, as hubby and I are leaving from LON on the 26th.

Last time we used the Eurostar, and never went to CDG; but we used the Metro/Tube in Paris.

It looks like we could easily take the tube from CDG to the Louvre area, without too much difficulty. Am I right? Or, are there issues that I am not seeing? Will we need Euros to buy the metro ticket at CDG? Or, will a credit/debit card suffice?

Thanks in advance for any and all info!
