Not sure what you are looking for in a room. All of the Couples resort rooms are decorated to reflect Jamaica, which isn't marble and glitz. CN rooms are very bohemian, CTI are recently renovated and felt like a breath of Spring air to me, light and airy, CSS rooms would be the closes to 'fancy', but still not glitz and glamor.
CN is the only other Couples resort that is on a long beach were you can talk walks. CTI's & CSS's beaches are in small coves.
The best rooms (in my opinion) at CSS are the ones up on the cliffs. They have incredible views of the ocean, but are not steps away from the beach. For steps away from the beach you would need a Beachfront Jacuzzi Suite, which is nice, but has a small balcony.
Any of the Oceanview rooms at CTI have incredible views, but the buildings are like high-rise hotels and there aren't any that are steps away to the beach.
The Beachfront Suites at CN are the ones closes to the beach and are steps away, but do not have a dead-on view of the ocean as all buildings are set at an angle.
For the most romantic, CSS wins hands down. The place is amazing. Lush vegetation with winding trails with surprises around each corner. Simply beautiful and it is the largest resort with the fewest rooms so it feels like you have the place to yourself and you are treated like royalty.
We also love CN, but for romance and a nicer room I'd pick CSS.
