28 February and 01 March look like being a gastronomic tour de force.  Lunch at the Hotel de Crillon,    Paris on 28/2.  http://www.crillon.com/crillon.html

On 01/3 St David’s day dinner at the Savoy hotel, London. http://www.fairmont.com/savoy/

Perhaps I need to join a gym?

And the fare from London to Paris via Eurostar is a wrinkly special of £59 return  (non-flexible, non-refundable, no frills & push up the hills) - which is less than the taxes you would pay if you bought an airline ticket.
