Boarding/Deboarding --
Though the boarding process is a breeze for suite guests, I cannot say the same for getting off the ship. We used Luggage Valet and were told we could exit the ship as soon as it cleared customs. However, rather than allow us to do so, we were ushered into the line of folks waiting to deboard with their luggage. So, an "easy walkoff" translated to a 45-minute wait. Celebrity should not advertise 'priority' de-boarding if it does not enforce the hype.
The Retreat --
I liked that the toilet and tub/shower are separate, so both facilities can be used independently. However, both sinks are HUGE, greatly limiting the counter space for toiletries and the like. Plus, the shower's half-door needs a magnet or something to hold it in place. The slightest nudge will cause the door to swing open, spraying water on the floor. The same can be said for the sliding door between the bedroom and living area. The slightest movement of the ship would cause the door to slide shut. Otherwise, there was more than adequate closet and drawer space.
Fun time as our guide included points of interest around Key West while walking between the pubs.
