This was our 21st cruise. We sailed on Celebrity in 99' and said probably never again. Eleven years later and eleven years older & wiser, Celebrity wowed us. We even booked a future cruise (open booking) w/ them.
Cabin was an inside--plenty of space, nice condition, decorated nicely. I'd suggest saving on the cabin w/ this busy of an itinerary because you are rarely in the cabin. Port days are approx 7a-7pm. Food and dining room service very good. Can't recall one thing that I didn't enjoy. Informal buffet good for when you are so dog tired that you don't feel like "dressing". We took formal clothes and never wore them. We did see one gentleman w/ shorts asked to leave DR to change at dinner. Ship entertainers were good. A few acts didn't make it or had ill members or family emergencies but ship staff filled in adequately. Not thrilled w/ Cruise Director. We were less critical of entertainment than we normally would have been b/c we turned in early to be ready for the next day's tour.
Used shore excursions 4/5 days--all were good except for one. If we went again we'd venture more on our own instead of using pricey ship excrusions (our excursions cost more than our cruise fair). This is an ACTIVE itinerary. We probably walked 20-30 miles over the course of the week. We returned home VERY tired but would do it again in a heartbeat!
