We are on board right now. Quickly, I will say that as this is only their second cruise, I am cutting them some slack, but ... Everything is VERY disorganized!
Our room is filthy and we seem unable to get it cleaned (at least to my satisfaction - Our room steward makes lots of excuses, and the purser's office says they will take care of it, however, our shoes continue to stick to the bathroom floor)! I have talked with other guests, and it seems to be "hit & miss" some rooms are well cleaned, others are like ours. Many people are unhappy with how cramped the rooms are, however ours (#343 Veranda Suite) size wise is small but okay, especially since we have the veranda.
The food on board is like everything else - Hit & Miss - In the dining room the food had been fine, although nothing special. It seems to depend on your wait staff, some people have had very poor (slow) service, while we have had good service (at dinner). Breakfast is a buffet. Lunch has again been buffet or very limited menu. The optional dining venues feature such fine offering as hot dogs, popcorn, and sandwiches (large rolls w/little meat) and bags of chips. Yum Yum !
Not much in the way of activites on board. Of course, it seems that most people are happy to just sit and read a book, or watch the river banks as we roll along. We have had two evening shows, one was boring, the other was slightly better. Same with the musicians, a couple are okay, others are ???
As I think of other things that might be of interest, I will let you know.
