Definitely, any of the Viator tours !!!

I would reccommend feet to see Paris. Driving around and looking at the outside of a bunch of buildings is a waste of time unless 3 or 4 hours is all you have.

Just go and see what you want. With feet (and Metro for longer distances) it's all easy.

Years ago on our first trip to Paris, as a family, we did the L'OpenTour for a couple of reasons - the kids wanted to ride on the very top (it was Dec!) and there was a stop literally a block away from our hotel. Also, at the time, our hotel gave us discount passes.

If you do this, you should consider doing a 2 day pass. It's only a couple Euro more than the 1day, and we found it very worthwhile. It has gotten considerably more expensive since our first trip. You might also consider doing the Paris public bus. The #69 bus goes all the way from Pere LaChaise cemetery to the Eifel Tower. You can find out more about the bus at http://www.ratp.fr/plan-interactif/cartebus.php Click on the route and it will highlight where it goes. Good Luck!

I found the L'Open tour to be a waste of time: tinny, pre-recorded information on tiny throw-away ear buds, and lots of lengthy stops while the drivers tried to solicit more passengers. It was free with our package from Costco, but I sure wouldn't do it again.
