I agree about some of the passengers acting like 2 year olds. At breakfast the first morning, we chose to wait for a 2 top table and one of our fellow guests berated the hostess for not being prepared. When they sat us in a newly opened area we didn't have the quick service we are accustomed to by the coffee server, danish server, etc and he made it known he was very unhappy. Sitting next to him was worse than slow service. I felt bad for the staff.
Glad that you both are negative! I hope my post helps people prepare before their cruise.
