You can use clubcard vouchers to pay for Euro Tunnel crossing, convert into airmiles to pay for flights or use them to pay for certain off-site accomodations
Used to be able to pay for Cresta holidays with Tesco Clubcard. We went to the Disneyland Hotel for 3 days, total cost about £17, about 3 years ago.... it was brilliant, luxury we could never have afforded otherwise. I was gutted when they stopped doing Cresta. Possibly your best bet is to pay for Eurotunnel using Tesco vouchers and/or a French Life apartment in the area.
You can use Tesco CC/Airmiles to book the onsite Disney hotel packages but it works out an expensive way of doing things.
I booked flights through Airmiles, cost me £200 of Tesco CC vouchers, but the flights priced up at just over £600, so not a bad deal. For the hotel/ticket package though I have converted vouchers to deals and sold them on Ebay, I've got just over half the deals value for each sale, not brilliant but cost less than booking via Airmiles, I booked via DLRP direct and will use the Ebay money to pay for the hol.
we stayed there in aug this yr,also got eurotunnel travel with it too
it was a fine base for DLRP, and easy to travel into paris too ,as the train station is close by
i am planning to to the same again in the summer
britchic has also stayed there, and has booked again for next yr ( twice! lol)
