Paris Day Trip

[Stevem5]

Hi guys.

I have booked a daytrip via eyrotunnel. I am due to arrive at Calais at 8am. How long fir mr to drive to Paris and where would I park or am I mental for even contemplating it? It's a surprise for wife she has always wanted to go up the eiffell tower and arc. I then need to be back at Calais for 10pm.

Thanks in advance
