If you are in town for Paris, I recommend venturing outward and spending a day in Giverny and a day at Versailles. As much as I adore Paris (and hopefully will finish compiling my Paris notes soon!), there is also so much to see outside of the city. Giverny and Versailles are top of the list, both due to the ease of getting there as well as the refreshing perspectives they give. I did this trip over a weekend as a solo traveler, and it was one of the most memorable weekends during my time in Europe!
