We were on the Viking Sky from Barcelona to Roma (11/12 to 11/19). We agree about Fatima in Manfredi's. She was wonderful as were the bar tenders in the Living Room (Alex and Karen). We found the rest of the food service a bit off.
I am also a bourbon drinker. When I realized that there was only vodka and gin in the mini bar, I left a note for the room service to substitute bourbon for one of the mini bottles. Evidently, they can't do that. Instead, he would leave me a healthy pour of bourbon in a glass each night.
