You need to be a bit more explicit. Do you want to build hours for a rating as cheaply as possible, or do you want to do some interesting touring, realising that that will be more expensive, or what.
If you simply want to get cheap hours then a dry lease of a 152 or cub, basing yourself out of Guernsey might be the answer, or refuelling at Shoreham or Lydd and doing drawback forms.
If you want to do the sights, and money is less important, then there is nowhere in the world to beat the West coast of Norway. The Greek islands are also wonderful.
Tell us your parameters.
