This was our 22nd cruise with Celebrity, 28 in all, you can see where our loyalties lie. I am decidedly biased.
We love this itinerary in February. Not a family oriented passenger load. I saw 4 kids. We were youngsters at 64 and 66. That does not mean the passengers don't have fun. Its just a little quieter after 11pm. Fine with us. We've done this itinerary twice out of San Juan, PR, this is the first out of Fort Lauderdale. I prefer flying into RP from Atlanta (where we live) but I did enjoy the two sea days outbound and inbound Fort Lauderdale. Celebrity has placed Summit in San Juan and offers two different 7d itineraries so, you can still do two weeks from there on B2B sailings ..... and Summit fares are a very good deal.
The Solstice class ships are technological marvels and, IMO, the best designed passenger cruisers in the world. Roomy without feeling like there are 3700 passengers milling about, stable, extremely reliable. For those worrying about propulsion failures such as those that occurred on Carnival Triumph, the likelihood of that happening on ships built since 2006, like the Solstice class ships, is remote. Different build standards plus the lead cruise lines, like Celebrity, are building extensive passenger safety back-ups into all their ships systems. Why? The bottom line. A mishap at sea of any kind will crush your business in a very competitive market place where capacity exceeds demand by quite a bit these days. Competition for passengers is fierce. Check out the ridiculously low prices on industry wide cabin offerings these days. If you've heard about the Azipod problem in Millennium Class ships, first, that has been solved in those ships and it was solved quickly; second, the Solstice Class ships don't use the Rolls Royce Product but rather ABB Azipods which have been trouble free on these ships since first launch of Celebrity Solstice in 2008.
