We will be arriving for our RS Paris & HOF tour a couple of days early. We will be in Paris for five full days, three on our own before the tour starts and two free afternoons after the tour starts. We have tried not to overcrowd the schedule, but on a couple of days, I feel like our interests will take us "far afield" and make for very long days. Take this day for example:
The tour group leaves together (from B Montmatre Hotel) and goes to the Ile de Cite, then a walking tour of the Latin Quarter. We are then on our own for (I assume late) lunch and I have my heart set on exploring the Marais (yes it's the only time left available for this trip.) It would be fun to take our time, and maybe stay out through dinner. But, that's a LOT of hours of walking, and really just a lot of hours away from the hotel without a break to refresh and head back out, but it doesn't make sense to go back and forth.
I should add, we are in decent shape for almost 60-somethings and we love to walk and explore, and this is our first trip to Paris. However, it is not our first trip to a large city where this can be an issue - our son lives in NYC, with there are similar logistics, and we have visited many times. He lives in Queens, and if you want to see Manhattan you pack a day bag and head out not to return until after dinner and hope that your feet didn't fall off!
I am always amazed at the ingenuity of the experienced travelers on this forum....and thought it would be fun to see what YOUR best strategies to deal with the long hours away from "home" on a day like this to keep it pleasant...and not ruin you for the next day.
