Paris in the Spring

What a cliché. But I can't wait!

I haven't been to Paris in eight years. Eight years! We've lived in France for four years and we've never bothered to make the trip. My sister is coming to France at the end of April and we're spending four glorious days in Paris.
She wants to go to the Louvre and I want to take her to the Picasso Museum and to the Rue Cler market. And the Jardin du Luxembourg and the Musée d'Orsay and Spring restaurant and the Marais and the rue des Rosiers where I want to try the strudel at La Boutique Jaune de Sacha Finkelsztajn and have her taste the thickest, richest hot chocolate ever at Angelina on the posh rue de Rivoli.
And, and and...

I don't think four days will be enough.
