I just got back from sailing on the Inspiration for a weekend with my mom friends and free of spouses and kids. (This is our third annual moms cruise). Fifteen of us boarded the ship on January 6th without issue. Although the ship was reportedly sold out, my friends and I all arrived at different times during the day with all of us reporting short lines and fast check-in. This was much improved over our experience last year where we waited in line for over 2 hours to get on board.
This is my first sailing on the Inspiration having previously sailed the same itinerary on the Paradise three times. The ships seemed to be virtually identical with exception of the water slide area which was much better on this ship.
Our large group opted for the late seating in the dining room and we were sat at two tables which were adjacent to each other. The menus were unchanged from last year's menu, the food was fine (good - not great), I enjoyed the soups and of course the chocolate melting cake.
