So envious Marcie, we have always wanted to do a Riverboat and this is one of the itineraries we have looked at. Agree that sailing by the eiffle tower during the light show must have been spectacular...they were doing that when we were in Paris in 2012 and we loved seeing it. Monet's home sounds amazing.
We truly hope to do one of these one day, haven't found anyone interested in going with us, but it sounds like it is easy to make friends and meet people so maybe we should just jump in and do it soon. Have fun, will look forward to more of your Rivermail.
