Help - my coolbox is broken and we go to France n week what shall I do?

[Lucky13]

As the title says - our rubbish Lidl coolbox has given up and we go away to France in 6 days time. I have no idea what to buy - heart says a 25l Icey Tek although DH would kill me for paying £100 for a cool box. Especially as a lot of people say that they didn't work as well as hoped.
I've looked at the igloo maxcold/ice cube and the coleman Xtreme, but am more confused than ever now.
We need something quite small (only 3 of us), not powered, as we weren't impressed with those, cheap but effective and able to be delivered quickly - not much then!!
Any suggestions anyone?

Asda and B&Q sell non-powered boxes for £20. For 3 people we take two B&Q boxes with bags of ice rather than ice packs and they are fine for 3-4 days.

ummme nay chance you can hire a fridage on site...
Oh and what's this about icey tek being not as good? Are there reviews?

We do have a really old coolbox - I presume that the new asda/B&Q ones aren't any better insulated than ones from years ago?

Hettie, one of the sites, we could hire a fridge but not on the other two. Mind you the price of fridge hire would buy a decent coolbox.

Re the icey tek - there seem to be quite a few people who say they only get a couple of days out of their box. May just be packing errors though.
