Where shall I go on my next veg holiday

The fuel tanks are getting low so I have started work filtering the 300L or so of waste oil that I have stored up. I have a bit of a trip to do this weekend but the rest will be filtered and then stored for my next big trip.

Still looking for ideas on where to go. The only limits are I would like to avoid France (as much as possible) and Italy. Its illegal there and I don't want to have to buy too much diesel/bio.

I was thinking possibly Poland, Czech republic, Slovakia or perhaps Sweden. If it wasn't for France in the way I would love to drive to Morocco.

Any recommendations ?
