Get ready for my all over the place, rambling review!
We sailed on Equinox last year for a 3 day cruise. I really wanted to try the Celebrity brand and we just fell in love. Previously we cruised Carnival and Princess. This was our 5th or 6th cruise. I'm in my 40's, BF is in his 60's.
Flew in the Friday before since weather in PA/Baltimore can be iffy in January. Took SAS Transportation ($15/pp) from FLL to downtown Miami. Got a room at the Hyatt Regency in Downtown Miami on Priceline for $115. Regular price was $269+. Got two doubles instead of a king but that was no big deal. The Hyatt is beautiful. We went to Whole Foods that evening for dinner and got cheap wine to take on board at CVS, both within a block of the hotel.
