It must be tiring trying to keep track of everyone's status. Each cruise is an experience unto itself and there can be any number of reasons why a certain venue is crowded. Personally, I doubt that most suite passengers would give a hoot whether they could go to Blu or not. When I want a change there are plenty of other choices including the buffet and room service.
It seems that one of the biggest problems is people worrying about what others may be getting. One thing I have learned in my fairly long life so far is to appreciate what I have when I have it and don't be envious of others.
