We cruised the Celebrity Summit Nov 22-29th, 2014. We stayed in Sky Suite 6118 which was category S2. Our group consisted of family members ages 42, 36, and 16. We had so much fun we booked another cruise on Summit next Thanksgiving!
Pros:
Speedy boarding process. No lines in San Juan when we were there!
Clean, spacious, quiet, updated decor. Plenty of outlets. Large closet. We actually used part of the closet as an impromptu changing area. Conveniently located to elevator and I-lounge. Nice layout.
