We were on the Galaxy for 2 weeks the middle of May and our friends just disembarked from a Med cruise last week.
We found that the ship was lovely - the only complaint that I had was that the front lounge (on the top floor) has the double windows fogged up - all except 2 windows. That was annoying, but not a big problem, we just sat by another window. The ship is kept spotless.
We were in a CC cabin - when we entered, the bed had two twin bedspreads draped over it - that wasn't acceptable (!) and so we asked the attendant to find a regular queen bedspread and also for some additional bedding.
The ship is old and you can find some tears etc, but it is well maintained.
We found that the service and food in the dining room was the best we have had in the last few cruises. We found it better than the Constellation or the Millennium - except in the extra pay dining room - which the Galaxy doesn't have.
Our friends had a balcony cabin and were very pleased with it, except for one day when they returned and the veranda had been painted and they couldn't enjoy it that day!
I predict that you will read all sorts of reviews, as everyone has a different experience, based on their expectations and their prevailing mood at the time!
We have never had a *perfect* cruise, but then we don't expect one, but we have had 17 WONDERFUL cruises!
