What to do in Paris on Christmas?

1) I heard that Christmas gets rather deserted in Paris (it's Christmas Eve when people come out to play, not the big day itself). So in view of that, I'm expecting several museums and attractions to close. Would any Parisians or visitors familiar with the city give some advice on what to do in Paris on Christmas[/i], please?

2) I don't want to clog up the forum space by starting a new thread so I'll throw in another question here: When would be a better time to visit EuroDisney in Paris[i] - 2 days before Christmas or the days following it? I mean, will there be a huge difference in visitor volume on either period?

Check with a local tourist bureau if you find one.

2 days before xmas, it will be quiet in Disney. After, even quieter. It does depend on the weather also. Obviously more will be there on a mild day than a cold, wet, snowy, windy day.
