Hi Kim,
DH and I did the Rhine and Moselle Fairytales cruise with Ama last year with the pre and post cruise extensions and it was fantastic! We lucked out as there were only two other couples for the pre-cruise, one other couple for the post cruise, and the cruise itself only had 45 guests with DH and I included.
We were in a suite and it includes bottle of sparkling wine on embarkation day presented by your butler, early-morning coffee service by the butler, non-alcoholic drinks in the mini bar replenished daily, fruit bowl replenished daily, daily laundry service (no limit on how many pieces of clothing per day), bath salts for the bathtub, and room service for dinner if you wish.
