One of the poor designs by Princess, that they never fix, is only having one drink station on each side of the buffet. Creates a huge bottleneck, plus the ice machines are always empty and they bring out containers of ice that people use all manner of ways to get ice. I bring ice with me from the bar when the ice machine isn't working.
They should have at least 2 on each side.
One thing I liked better on Celebrity was multiple drink stations all over the pool decks.
