If you time your trip right, there's a gorgeous little gastro-pub / B&B on Mercury that you simply must visit.
(If you time it right, Mercury will be closer than Venus, and the Continental Breakfast they serve there is just divine - it was in all the Sunday supplements don't-you-know.)
Best of all, take the 4x4 as far as you can go - we did. We only got the bikes out once we'd nearly reached the top of Mons Venus , of course, as young Tarquin and Chlamydia are too small for the full ride - but the Landlord chap agreed that we were really in our element.
He even suggested a destination for next year's hols - Alpha Clitorri , we can't wait, as it sounds like it will suit us to a tee.
I hear the locals are frightful, but since we have already paid in full (First Class, All Inclusive), I don't imagine we should be meeting very many of those, thank-you-very-much, except the ones that do that do the authentic local dancing.
Best Wishes, Aunt Graptolite
