We were on the Seashore out of Port Canaveral for a 3 day cruise. The cruise was full with about 4000 guests. We've only been in Sky Suites on Celebrity, and we had a Deluxe Suite on the Seashore, a comparable cabin. Storage and balcony were superior on MCS, but cabin outlets were much better on Celebrity. The bathroom was better on Celebrity. The sundeck on MSC was by far the most enjoyable part of the cruise.
