I've booked a week in Paris for our 1-year anniversary in early September. We are staying at the Hôtel Observatoire Luxembourg on the left bank, which I carefully selected for it's proximity to the Latin Qtr, Lux Gardens, etc. I'm guessing I should pre-buy a bus pass and/or a metro pass? We will also likely get the museum pass. The only other thing I'm thinking is that we should book some excursions (Normandy, Monet, etc.). Any thoughts or advice appreciated!
