Hi Gardener46 & welcome to cruising!
I have found that when researching message boards & in looking at reviews of ships, it's best to throw out the highs & lows & try to look at the majority of the comments. That is where you will get your most accurate info. A great tool to use right here on Cruisemates is the "rate your ship poll" section under "Cruise Reviews" at the top of the page. You can compare up to 3 ships & see at a glance an overview of different ships. For example if you compare, say, Celebrity Infinity to ships of another comparable line like Crown or Sapphire Princess, you get a picture of how a number of people rate whatever ship your interested in. I use those 2 lines as they are the lines I have cruise, & I find them to offer a similar product
Those who are always for or against a particular ship or cruise line, are usually not going to give an accurate assessment as the vast majority do.
Again, welcome to cruising & enjoy your retirement!!!
