Rich, glad to see you are "coming out of retirement". Here is a suggestion from the left side of the field;
rent out your house for the UK winter
hop on a plane and fly to New Zealand
rent a camper or motorhome and go for a drive.
then if you have some time left there is plenty to see here on your way home.
Why NZ ? The weather is cooler than AU but generally warmer than UK (pre global warming). The terrain and scenery is nothing short of spectacular.
Because it is so compact you do not need to drive long distances. The NZ people speak a variation of English and are friendly, even my Sister married one! Oh yes I almost forgot you have taken tea with Steve on our last UK narrowboat trip. The rental fleet in NZ is much more varied than AU with many UK/EU models available as well as locally made offers.
Interested in your thoughts.
cheers,
