bel110 - I think you're right. I seem to remember that last year one of the contestants was upset because she couldn't see her child because the only day off was Sunday and that was not enough given the distance. I think the routine was:
Monday - debrief at Le Manoir and get challenge
Tuesday - prepare challenge
Wednesday- challenge
Thursday - one couple goes home, rest prepare for weekend sevice, including mini-task.
This year we know from close-ups of tickets that the fast-food trial was June 16th, so the restaurants didn't open until after that. We know from my link in the post above that the Food Fair demo was July 10th 3 weeks 3 days later in real time but 5 weeks later in programme time or in terms of last year's timescale.
