Our final day of Austrian fun is as perishingly cold as before, but this time the snow comes in blizzards, blowing gustily around us as we tick off the sights. But fortunately these blasts from Narnia take their time to arrive, allowing us to explore the jewel in Vienna's crown before the whiteness comes down.

Ah, the shame of humiliation. Here I am, ladling museli into a bowl and about to grab a coffee in the executive lounge when an officious fraülein accosts us and demands our room number. "We're in room 1039", I reply, secure in the knowledge that as Hilton Honors members we are on the tenth - and executive - floor. “But you are not allowed in here!” she replies. “Your room is on ze tenth floor, but it does not give you access to zis lounge. You must leave now!” she exclaims, almost grabbing the bowl from my hands. “Breakfast for you iz downstairs in ze lobby and you must PAY!!”

It's been six weeks since I returned from my yoga retreat in Portugal and I’ve been following my new lifestyle regime with the fervour of the freshly converted, saluting the sun every morning and stretching myself into all sorts of yogic positions… but it seems I’ve been rather too enthusiastic. A simple mis-step halfway through yesterday’s session means I’ve sprained my big toe and am hobbling around in pain, which is rather unfortunate considering we’ve booked a walking tour of Vienna to celebrate the fifth anniversary of our civil partnership.
