Guided tours - not into Paris

[TinkSassy]

Starting to look at a trip in spring. I have no issue getting in and out of Paris via metro but refuse to drive. I took a guided tour last time to the Loire valley which I loved but was difficult as I had to get to city center by 8 and that was stressful with the distance. Wondered what other options are available either with pickup in the dlp area or that we can grab a train and then walk. We will do - 2 days at dlp, 2 in Paris, 1 at Versailles, which leaves us 2 days to work with. We will stay at Marriott at dlp the whole time as it is free for me - makes it worth the travel issues
