This was our fourth cruise within three years having previously sailed with Celebrity, Holland America, and Princess. We are a couple in our mid-thirties.
We chose this cruise because it fitted in with times we could both take holiday, left from a UK port, and was going to places we hadn't been before (in France) - a final important check\consideration was that Crystal was reasonably well rated well by recent passengers.
The ship was in superb condition, arguably better than younger ships; everything was polished, clean, and in 'close to new' condition. A fairly small ship by today's standard we found it to our advantageous as it cut down unnecessary time walking between different venues. A similar size to Ryndham (Holland America) however a key difference we observed was that it never felt crowded on Symphony, in fact it was the least crowded ship we've sailed on yet. There are potentially two reasons for this; either it was undersubscribed (possibly because people concerned about terrorism), or the age of the passengers meant they slept a lot or otherwise entertained themselves - possibly a bit of both.
Absolutely fine, no smaller than other cabins I've been in (and this is the first time I've not had a balcony). Bathroom was spacious and had a bath as well as two sinks for him and her (or him and him!). The cabin attendent kept it in great condition though we didn't get any towel animals. Big wardrobe with lots of hangers, a couch and table.
As an E1 cabin it had a limited view, so some of our window was obstructed by a boat; I do not regret saving £300 (~$400) in place of seeing a full skyline (I will try and attach a photo), it really wasn't as bad as I feared it could be.
