I am not sure what the original poster meant by "deal" with the buffet, but I assume it is the same as every buffet. Look for an open table; which I don't understand, we just sit where there are two empty seats, meet new people.
Then hope your food is the correct temperature. Wait online and someone always has to slip in front of you because they only wanted that one thing; the same thing you were waiting for.
Then if there are tons of kids; they are running in between people while you try to juggle your plate, drink and camera bag.
Oh, well, that's why on the Royal Princess we LOVE International Cafe and Alfredo's.
