i worried about dining with stangers also. i live a pretty sheltered life as far as getting out and rubbing elbows so to speak with more social persons than myself. but i went to the dining room every night and loved it. my table mates where so friendly and nice. and carnival sat me with other singles. but if you want to do room service im sure you will have a wonderful meal. how about going to the lido deck or other more casual food area too eat at night. you can set by yourself and people watch. have a great time.
