We cruised this time with my adult daughters, we had cruised with them before when they were teens. They were 12 and 19 before, this time 22 and 28. Back in 2002 we cruised the Carnival Jubilee which is no longer in the carnival fleet, this time of course was the Liberty. To sum up we all had a great time this time. I find that the in between years of teenagers are not the best for cruising. The young ones enjoy camp carnival, the young adults enjoy everything else, but teens, in my opinion, have a harder time fitting in.We departed in Miami, a very smooth process at port, now no personell are involved at check in - just a machine and kind of do it yourself ATM type thing. This is not very personal but faster. There are still Carnival staff to help you if you need it. We were aboard by 11.30. We were to set sail at 4 but there was a security problem with some passenger on the ship, we were delayed until after dark. No problem as they said our ports would still be on time and they were.Our first port was Cozumel and although my wife and I had been here many times this was hte first time we had taken a "Fun" excursion. Definately do the snorkel and beach party if you want to have a good time. I guess it was better because we had our daughter there to enjoy it with us. It is just as the brochure says it is - maybe better!Grand cayman was next. you don't dock here so be prepared to tether in on another smaller boat, this is no big deal but be careful of your step. We had been to Caymans before so did no excursion here, however we have before. The Turtle and "Hell" tour was OK but overrated unless you REALLY like Turtles.Jamaica was next. This time we went out on our own to find a Beach Party. I want to say now you will get hounded by all the locals to buy, and I mean hundreds, just be polite say no and be on your way. A nice tip: Right behind Margaritaville is a nice beach: free for patrons of Margaritaville!Now for the ship itself. Carnival Liberty was very nice as all Carnival Ships seem to be. This is our 6th cruise and 5 of which have been with Carnival. They really know how to do FUN. We don't particularly care for all the "High Brow" stuff found on other cruise lines. There are 2 formal nights on this 7 day cruise, I could do without one of these! The staff and crew are always very nice and polite. Food is good too. I always try to go to buffets late or early to avoid the longest lines. There is always someone near to try to sell you drinks which is OK I guess. I don't drink that much so it can be a little annoying. Entertainment is always good, especially the production shows!All in all a great value for the money as long as you watch what you drink!We plan to cruise Carnival much more!
