We don't know where we're staying yet. We're working with a travel agent (which I never do!) and I think the hotels she sent us that I liked were near the Tuileries. I think. We need to be a reasonable metro ride away from Roland Garros.
I'd love to go to Versailles, but since we only have 2 full days and two of them will be tennis, it might not happen. Maybe before we catch the Eurostar to London.
Maybe I'll keep my eyes peeled for a show in London, I think that's a good prize for me after sitting through 18 hours or so of tennis!
I'm going to jot all of this down!
Versailles would take up a whole day if you did it so I wouldn't advise it if you're limited on time.
Last time I went to Paris my sister and I went on a boat trip down the Seine which was pretty interesting (you can buy tickets immediately before if you don't want to be tied down- just head down to the river by the Eiffel tower). We did it at sunset- so you can go up the Eiffel tower in the daytime (definitely worth booking a time slot ahead of time if that's what you want to do, otherwise you'll spend hours in a queue), then by the time you get to Notre Dame it's lit up, and the Eiffel tower is lit up by the time the boat gets back.
I definitely second Montmartre, I love it there.
Walking from Place de la Concord to the Arc de Triomphe down the Champs Elysees is something you have to do, and some of the cafes aren't toooo ridiculously priced, but obviously if you walk back a few streets they get cheaper.
I've never really done London as a tourist (I really should, maybe that's what I'll do today!), but the London Eye is a good way of seeing the city. Also if you walk across Hungerford bridge you get great views both ways. And there's a cable car across the river if you go a bit further East (it goes between North Greenwich and Royal Victoria) that I keep meaning to do.
The changing of the guard is interesting to watch and doesn't take up much time.
If you want to see a show you can often get really cheap tickets on the day of the show either from the theatre itself or from a place called TKTS (there's quite a few touts pretending to be TKTS, so worth looking up where it is/what it looks like if you do want to use it). But that depends on how set you are on watching a specific show, because they won't all always be available.
I'm sure I've forgotten stuff but I'll let you know if I think of anything else!
Wow sorry for the novel, it's nice to know the places people on here are talking about for a change!
