For Paris, we did a week in an apartment in the city, followed by four nights at DLRP. That might have been one night more than we needed at Disney, but the Studios park was also a lot less interesting then, so maybe that would work now. We kept ourselves busy for the first week almost exclusively with museums. My favorites are the
Rodin and the
Orsay. The
l'Orangerie is small but a hidden gem; the Water Lilies series is stunning. I suppose you have to go the Louvre, but I find myself skipping it as often as not. Somehow I still have not been to Versailles.
