Hi, just my humble opinion....I have cruised Carnival 3 times once in the 80's, 90's, and 2006, and you couldn'tgive me a free cruise to get back on. I have sailed with RCCL 14 times from 1993 to the last in Feb on the Granduer. I noticed in your back and forth with Figee who gave you alot of great information on AOS, which I also sailed on in a similar intinerary on in 2006. We may have different needs and wants in a cruise, I do not sail with a teen, and I have been fortunate to sail 20 different times, with RCCL my obvious favorite. A middle ground cruise as you described, I have sailed solo about 10 of those cruises, and despite the bad publicity, I have found it a very safe, relaxing way for a working girl in her 30's and now 40's to sail solo. After all that rambling, I am not a big ship girl, and loved my cruise on AOS, but found it HUGE. I went with another couple and they love the newest and best cruise, but not me. In your case, you talk about the newer ships which are getting bigger and bigger, so I think that is something appeals to you. I reccomend the Adventure, but remember sailing out of San Juan gives you a great Southern Caribbean itinerary, but the ship is likely to have alot of Puerto Ricans. I am not saying this is a bad thing, but many others have commented on the different cultural differences. I found the teens to be rude and not well supervised on the AOS. For that reason I would also reccomend you check out any of the other Voyager class ships, the Explorer, Navigator, Mariner or Voyager, or even the Freedom class, Freedom, Independence and Liberty that will give a great Eastern or Western cruise, with a ship full of fun things to for your whole family. My comments on AOS may sound bigoted, but they are echoed all over cruise boards. I love sailing out of Peurto Rico, but would not again on a big ship, that gives big discounts(such PR children sail free) to allow the ship to sail out of PR. I would do another Windstar cruise, which I wouldn't reccomend for teens, but an adult cruise with great itineraries. I would be happy to respond to any other questions, or comments.
