In my discussions with people over the years, I have found that people either love cruising or simply don't like it. I often times have trouble dealing with lines and inconsiderate people who think of no one but themselves and often get frustrated with situations similar to what you previously described. I guess that since I know what to expect that I am able to overlook those things and simply enjoy my trip. I get so excited leading up to my cruises that the last month or so, I can think of nothing else.
Don't ever think that forums such as these are not the appropriate place to discuss problems...the longtime members on here are an absolute treasure of knowledge and can sometimes even try to help in ways that you can't imagine. I would simply suggest a bit more tempered approach to posting about the problems in the future.
I have thoroughly enjoyed this discussion and look forward to many more just like it in the future.
