The Equinox is exquisite. This was our 16th cruise (we have sailed on Celebrity's Millenium, Mercury and Summit, as well) but the Equinox strikes the perfect balance of offering lots of possibilities without seeming too loud, too crowded, too gaudy or too big. Our cabin was on the deck 7 (7223) and was straight up to the Lido and straight down to the Silhouette dining room (we've traipsed miles to get to cabins in the aft in the past). There was a wonderful big meeting area in front of our cabin, with a table made from an enormous slab of burl oak, which people used throughout the voyage to play cards, read or talk. Very peaceful and inviting space with a live tree suspended above the decks in the elevator space- you have to see this to appreciate it.
The balcony had two chairs, which semi-reclined ( a nice touch!) and a table big enough for breakfast. Our bed was next to the sliding glass door and was made up with the fluffy duvet which is both light and warm. The flat screen TV frees up room on the desk, and the hair dryer actually fits away in the desk drawer (sometimes they don't, quite.) The lighting in the cabin was good, with a dimmer switch and a lighted phone by the bed (so bright we stuck a pillow over it at night). Cabins can get very black at night, at sea, and the bath had an ambient light that is just bright enough to get you in there in the dark, without keeping you awake all night.
We used the wake-up call feature on the phone, and liked the info available on the TV. You can view photos there instead of wandering around the photo deck, and it was handy to check our account balances and order excursions from the cabin.
7223 is straight down from the Lido, straight up from the dining room and close to elevators. Deck 7 is very quiet. The "Team Earth" meeting room is a nice area, handy and behind glass doors. The bed in 7223 is by the balcony. Wedge a piece of paper between the glass panels on the balcony, though: they rattle.
