Shuttle buses provided by the cruise line were overpriced - ranging from $10-12 each way. Most of the ports were not within walking distance from the ship and some form of transportation was required. Antwerp was very close but the others were not.
Getting money in Gibraltar was a challenge. There are many exchange booths but it's hard to find an ATM. Seeing those apes was worth it though! They have their own currency but will take Euros. This does not work in your favor.
The ship had a lot of creaking and clanging. It moaned most of the day and sometimes into the night. They did make an effort to correct the problems.
They are cutting corners in the entertainment area. We had two production shows - one of which I had seen years ago. The last time we cruised on Century we had the most outstanding performers - but this time we had the same people for several night in a row but just paired up with new partners form a previous night. Blame the cruise director for this.
Celebrity is apparently switching from the old fashioned trivia games where you compete and write down the answers to win a pen or some little item. Now they have high tech video games which are just awful. I suggested they throw them in the ocean. On two of the three sea days there was very little to pass the time in the way of activites and games. On the third sea day after I spoke to the activities director they did have several trivia games but it was kind of too little too late. Good thing we play bridge or we would have been totally bored. The enrichment seminars sometimes didn't make the daily schedule and if you didn't watch the TV announcements in the morning you just missed them. These were also kind of out of sequence. For instance, they did Paris the day after we left.
Food overall was good - sometimes not as hot as it should have been. The pea or carrot flan were disgusting and we wondered why the next day there might have been soup of that flavor.... Wish there was a way to keep the pastries from drying out. Rolls and donuts needed dunking to be able to eat them.
Celebrity was disappointing this time and I think I'll try some other cruise line for future cruises.
