I was on the Galaxy 25 August 2006 and experienced the Galaxy as ship with a very hardworking and superfriendly crew, superb ambiance and nice layout. The interior of the ship is well maintained and to my surprise, this aspect of the ship doesn't need to refurbish this or next year.
The exterior is a different story. Although the ship is very clean, the pooldeck, pools, floor, outside walls, chairs need definitely a refurbishment. On top of that, the 4 whirlpools were out of order, the kidspool (1 day), the main pool (first day) and de T-pool (1 day). The crew was constantly painting chairs (!), varnish the wood, replacing some warningshields at the pooldeck, replacing the ceiling of the kidspool etc. The exterior looks very old and needs to repair thouroughly.
The ship is really clean and although the exterior was a bit disappointed to us, we had one of our best cruises. The itinerary, crew and food was excellent and it might sound strange, but overall we loved the ship (interior is bright white) and I would definitely sail on her in a heartbeat.
