As our next trip is booked over a weekend, we're considering tagging a few more days on the following week and using Saturday and maybe Sunday to visit Paris, because we all get grumpy when the park is full. We want to see the main tourist sites and visit the Catacombs. Need help and advice deperately, was intially thinking of booking the Paris Essentials tour to see the sites as it seemed like the easiest option and they guarantee you'll see all the main ones albeit from a coach with a couple of free hours and more importantly collects and drops off at the NPB. My quick look at a map though suggests that we might have to do the catacombs seperately and have to negotiate the rail network to get to them So now I am thinking if we have to do that for the catacombs, might we do it as well for our sight seeing day. Any help, advice, experience, tourist plan very much appreciated.
