I started researching to get us ICE train tickets to get the best price and http://en.voyages-sncf.com was the best one. Plus I got them 90 days out so I scored some great deals! It was around 100euros per person round trip, same day. Normally, they run 130euros one way.
We left my house around 6am and walked to my village's train station to get to Kaiserslatern hbf to board our ICE train to Paris. Just shy of 3 hours later we were in Paris. We walked across the street to board our Hop on/ Hop off bus which we used all day. What I loved about this specific company, L'Open Tour is that they had 4 different routes you can travel around on and see more sights. We started on the yellow route and than transferred onto the green route. We got off at only a few of the main attraction sights since we had to be back at the train station by 7pm to make our train home.
Au Revoir Paris!
