Hi, I hope you will enjoy your Summit cabin and cruise. Last August, my husband and I went to Alaska and we were in Cabin 9133. Celebrity had upgraded the 1A cabins up to Concierge. It was nice - champagne upon arrival, hors d'vors at 4pm daily, fresh flowers, chocolate on our pillows at night, and little boarding perks for the excursions. As for the noise... we never heard any from above or below - no chairs scraping, no running sounds, no nothing. You didn't ask about the overhang. Well, even though we had excellent weather, we still got plenty of daylight. We used the verandah lots and enjooyed it a lot. It is true you cannot see straight up with the overhang but it wasn't a problem otherwise. We left our verandah door open all night and it was great having the feeling of more privacy with the overhang. It was a great cabin and a great cruise. Next summer I am returning to Alaska and taking my Mother along with my older sister. We will be on the Infinity and using an aft handicap room. Enjoy.
