The Infinity re-positioning from Valparaiso to Fort Lauderdale was a second chance for us with Celebrity. An earlier cruise about ten years ago left us wondering and we hoped for something better this time. It didn't happen.
I'm not going to write a blow-by-blow. Other reviewers with more time can do that. But briefly,
The ship is fitted with attractive public areas, and our cabin (8045) was comfortable (and included an oversize triangle shaped balcony--very pleasant). Our cabin service attendant did everything we asked, and the cabin and bath were always well cleaned and supplied. No complaints. However, there are signs of wear (like rust in the shower and on the balcony) that we expected the recent refurbishing would have covered. It didn't.
Good balcony; larger than usual triangle shape. Concierge class has some nice extras. Good access to forward elevators. Convenient to Celebrity theater (Deck 5) and Constellation Lounge (Deck 11) using those elevators. Long walks to aft section where dining facilites are located.
