Travelling from the U.S. to Paris and visiting DLRP for one day the week after Easter. How are the crowds? Depending on weather, is there a better day of the week to go?
If I had to pick one weekday I'd probably go for a Wednesday. I'd certainly stay away from Monday's and Friday's as they seem to be the busier of the weekdays.
The local schools are on holiday that week plus some schools in the UK so I'd definitely avoid the weekend. As cap'n said Mondays and Fridays are always busier than Tuesday, Wednesday and Thursday.
Schools in Italy are off til the Wednesday after Easter.
I have been there the weekend BEFORE Easter and it was mad.
I would say go for thursday or friday after Easter.
