Hi Stringbean
We drive down to the South of France several times a year and we always use the tunnel.
This is for a couple of reasons - one, DH and I are not ferry fans and two, we use Tesco clubcard rewards and it means we pretty much travel for free. Tesco vouchers are worth 4 x their face value for Eurotunnel, so if you have £25 of vouchers, this buys you £100 towards Eurotunnel.
Don't bother with the flexiplus, the tunnel is very flexible anyway, especially if you are a standard height car (no roofbars and roofbox or bike on the top).
Basically, if you arrive before or up to 2 hours after your scheduled departure, they just put you on the next available crossing. You do sometimes have to wait a bit, but never too long.
It is quite boring on board but as it is so fast, the time passes slowly and you are on and off in about 40 minutes.
We often take the time on the tunnel to eat - a tip is don't put your picnic in the boot as depending on where you are put within a carriage, you sometimes can't open your boot due to the car behind being so close!
Do ask if you think of anything else, lots of people on Mumsnet use the tunnel.
