OK some random thoughts on this long thread: I've been on 4
DCL cruises, and NEVER had a problem with seating. On the last one, with my extended family, we had a plan to sit to the right side of the theatre where the seat break is located. At each of the shows, we did this, and never had to "save seats" We usually picked the end of 3 rows so that we weren't stretched out along the row, but clustered together. It also helps others since we're all over 5'10" with the exception of SIL who is a petite 5'2" and looks lost in the land of the giants. I know it may seem easy to "slouch" but as a tall shy individual most of my life, you would not believe how uncomfortable it is to slouch during a movie--nothing like seeing a show and then having to see a chiropractor. Besides, we have never had a bad seat.
I am guilty of pulling a chair into the edge of the water to enjoy the cool water on a hot day. I don't think I blocked anyone, but if I did, I apologize.
It is impossible to micromanage ones' vacation. (I don't mean plan--I am one of the many planners among this group--I mean trying to manage and cover every bit of the trip) If you think that you can plan out EVERYTHING and have it work perfectly, you will be disappointed. We had one poster on this board who tried to micromanage everything on her cruise (and I mean EVERYTHING) only to find that 2 days prior, the trip was cancelled. Stress is a result of unfullfilled expectations, or lack of control over things. If you go with the flow, and RELAX, DCL will give you the most relaxing and special vacation that you can imagine. If you try to control everything, Good Luck--you're going to need it.
Finally, I remember reading one time in Emily Post or Miss Manners that it is just as rude to point out someone else's lapse of manners, as it is to have a lapse of manners. We never know the true story behind another's behavior, and we really can't change anyone else's behavior. It is doubtful that the rude person will ever learn anything from our comments, or even recognize themselves in the comment. On our trip to the UK, I was being to get perturbed by all these people going the wrong way on steps, sidewalks, etc.--until I realized I was the one going the "wrong" way--It's keep right in the USA, keep left in the UK.
