I have already booked quite a bit in advance but I am also not knowing how much we'll be up for our first day, yet arrive at 7 a.m. April 1 so I would like to take advantage of that (and we will stay awake til an early bedtime).
Specifically:
Marmottan Museum (hoping on day 2 after we return from Giverny)
Rodin - hoping to see this on day 1 (April 1 Tues) , quite close to our hotel
Invalides (same as Rodin for timing we hope)
Pantheon -- I don't see timed tickets, just an option to buy a ticket to use within the year, is that what they offer? It was on their site.
Arc de Triomphe (tentatively Saturday)
Cluny (tentatively Sunday, but I also want to visit St Sulpice in the a.m., and will likely book timed catacomb visit this day, tour begins at 4 p.m. Sunday).
My 15 yr old daughter and I are on the Rick Steves' Paris tour that begins Sunday April 6 but we booked 5 extra nights pre-tour (non post) but I am primarily just wanting to know how lines will be if we wait until day of to get any of these tickets.
