Bonjour!
A few years ago, we stayed at the Hotel le Perigord in La Roque-Gageac. We had a room on the back side of the hotel and we could see the lights of Domme at night. It was so quiet and beautiful to look up at the lights. The hotel is mentioned in the Dordogne section of the RS book.
On Trip Adviser, it is rated #2 for hotels in R-G. I am sure Hotel Belle Etoile is rated higher with higher prices. It is also located in the town of R-G. Hotel le Perigord is outside of R-G but not far! I believe Hotel le Perigord is less expensive. It is part of the Logis chain. Some of the Trip Adviser postings commented on refurbished rooms. I believe this would have been done since we were at the hotel. Plus, the food was really good at the restaurant. We used it for breakfast and dinner. There was a large self parking lot. We had a car so it was easy for us to visit lots of other sights.
From R-G, towe were able to drive to Sarlat, to the Lascaux II. Even though Lascaux II is a replica, I thought it was very interesting. We did not go to any other caves. We had lunch in Les Eyzies-de-Tayac. The National Museum of Prehistory is located there. I wish we had gone to the museum, especially after seeing RS visit it on his Dordogne TV segment.
We took a boat ride (not a canoe trip) on one of the small tour boats that are on the Dordogne River. At one time, the style of boat used was for transporting goods down the river. We also visited a "fois gras" farm. We saw the geese and ducks being fed. The geese didn't seem to mind too much because of their long necks but the ducks were not happy! The price paid for enjoying "fois gras".
I hope this helps with a bit of information for you. We really enjoyed this area of France and do plan on returning at some point.
Au revoir!
