My daughter and 2 granddaughters (12 & 14) and I are coming a day early in London and staying a day later in Paris. Surprisingly I haven't found any trip reports from this journey that give much detail. I'd love to hear from someone who has gone recently. Also, I'd love recommendations on what to do the 1-1/2 days before in London and a day after in Paris. In London I'm thinking of finding a place for high tea or go to Harrods or Selfridges, Westminster Abbey. In Paris I'm thinking of a Seine river cruise, Montmartre, Musee du Parfum, Galeries Lafayette. Thanks for any advice.
