We were cruising on Infinity RT LA-Hawaii for 14 days, from 10.22.06 to 11.05.06. Here's my review about the cruise and the ship. It is quite long, but I tried to make it more or less comprehensive, so deal with it.
Our short background. This will help you to adjust/level up our observations. My wife and myself are in our late 40s-early 50s. We cruised 5 times before Celebrity, with 4 different cruise lines, ranging from Radisson Seven Seas to Royal Caribbean, so one may consider us as somewhat experienced in cruising. We came to the US from Europe (naturalized with over 13 years of living in this blessed country), so in addition to the age/experience factor, we have fairly unbiased opinion with regards to what's expected by both Americans and Europeans from a cruise trip in general. This is important because on every cruise ship you see people of various nationalities and ethnicities - cruise reported here was not an exception, we had a large group of German tourists, and all PA announcements were made both in English and in German. We also belong to a more physically active kind of cruisers, enjoying swimming/snorkeling (to a great degree), sports, dancing, etc. We like to explore ports to the fullest, using every chance to look for far-from-ordinary attractions and places.
About this review. I express here our (and our only) opinion, based on thorough study of the Internet data, scrupulous observations during the cruise and conversations with other cruise guests and crewmembers. If you'd find this review atrociously wrong and shamelessly partial - sorry, can't help you.
