you will either love it or want to go back to big ship cruising! Here are the pros and cons:
Pros: Docked right in the town and no lines to get off the boat; ship was lovely and service was very good; cabin storage was good; intimate setting; wine flows freely (and "free") at lunch and dinner; bed was very comfortable; no noise from other cabins
Cons: Priced substantially higher than cabins we've had on big cruise lines; food was not exceptional, only good most of the time-best meal was lunch because of the great salad bar; cabins are very small-hardly room for two to move around; passenger cliques were more noticeable ( and audible), of course, because of the smallness; very small "gym" where you can look outside and see the staff smoking...
Our boat started in Arles--not Lyon where we disembarked. Arles is an interesting city for a day, but we stayed several days on our own prior to the cruise-and that was too much. The first day we were kicked off the boat because it had to go into dry dock to have a propeller replaced. So unfortunately we had to tour Arles again (were planning on sleeping in) and be off the boat by 8:30am--then we were bused to Les Baux, a beautiful mountain town. The latter is typically a non-free tour but because we were displaced for the whole day, it was comped. The rest of towns were interesting, especially Avignon where we had a terrrific guide. Lyon is delightful because it's a large city with great restaurants-we ate lunch at Le Sud-terrific!
So-a river cruise is interesting, but I prefer the larger ship with more space, more good food variety and larger cabins.
