I travelled with a friend on the Oasis of the Seas on the Sept 18/10 itinerary, which included stops in Haiti and Mexico.
Both of us are females and were in minority for this cruise as part of the under 40 crowd.
This was my fourth cruising experience. I've been on Carnival (which I enjoyed, particularity the festive vibe and food), Costa (which I enjoyed the least of the three, but we went because it was the only one available for an Egyptian winter cruise), and Celebrity (which I liked as well but was a bit bored since its geared more for an older crowd).
Our room was fine for two, a bit small, quiet location, never heard any hallway noise.
