Nice but a little disappointed
My husband and I set sail for a Thanksgiving cruise aboard Oasis. This was our 6th cruise and 2nd with RCI. My disappointment is mostly with how infrequently you see the ocean. This was the only cruise I've taken where I felt like I was in a mall rather than a ship. They do a lovely job and the service and room were excellent so I can't really fault RCI. My review has more to do with preferences.
I like the Freedom and Voyager class ships better due to layout. I was not happy with the movie screen being in the AquaTheater - it was rarely used by anyone. I also didn't like that on Oasis the jogging track is on deck 5 (I think) behind the life boats. I prefer it to be at the top of the ship where you can enjoy the ocean views. I am thankful we had a balcony so I had a view as well as a quiet place to read or have breakfast.
I recommend Oasis only for active families with kids since this is not what I'd consider romantic for a couple. Again, due to preferences. Oasis is too large and doesn't feel enough like you're at sea to me so I will stick to the smaller ships or Disney Cruise Line.

Make all of your evening show reservations as soon as booking them is available, usually 90 days before sailing. Also, do not miss the Quest!
