we usually cruise on Oceania (penthouse suite) however Celebrity had an itinerary that met our needs. We were very hesitant about this because it is three times larger than we are used to. We were pleasantly surprised. This was the British isles cruise.
Cabin
We booked a Sky Suite 2. The cabin is a nice size however the bathroom is small with a tub/shower combo. It was very high and hard to get into and out of. The maid and butler service was wonderful. Orlando (our butler) was very disappointed with us because we are very low maintenance. He was always available and brought us treats even when we didn't ask for them.
