We used The Key once previously... mixed bag, but overall was positive. Like a previous poster mentioned, we boarded well past lunch on embarkation day but they offered us another day to compensate for that. For us, the best part was the assisted debarkation. Basically this was a ship's officer escorting us out of the dining room and walking past hundreds of people waiting to get their luggage...we walked right up to a small section that just had Key luggage, grabbed our stuff, and went right to the customs line. It saved us a LOT of time standing in line that day. As that was our favorite part, I feel like it's a better value on shorter sailings (since it's a per-day fee).
