I dont think there are a bad table in the dining room either. The table mates are one of my favorite memories of the cruise.
BUT on one cruise we had a table mate...a married man traveling single ( i think we can all imagine what he was cruising for) and was very offensive. Since my sister and I travel without our husbands (with their blessings) I think he thought we were going to be his next "victim". We were very offended, needless to say we went to the matre de and he moved us after the first night...
