When To Drive to Le Mans: Wednesday Vs Thursday?

Hi all, second time around going to Le Mans, but first time with a ‘proper car’ (4 people in an X308 Jaguar XJR) and first time being able to drive down on either Wednesday or Thursday as opposed to late on Friday night. The question is which day should I drive down on? I want the maximum Le Mans experience with the most amount of people driving down there at the same time, the options are get a morning eurotinnel on Wednesday, or a morning tunnel on Thursday. I hope you can all help me out!
