I haven't read much of the reviews here nor have I been in the forums much lately, I'm just stopping in quick to give a few comments on our recent Allure cruise FWIW. (be ready for random memories, forgive my brain for not being very organized)
First, I hesitated booking on RC again and felt the big ship required much too high a price. My wife won that argument. Glad she did.
Stayed in a D1 (larger balcony) cabin. For just 2 people the extra balcony room actually wasn't worth the extra price. We booked on the port side, which was NEVER the actual port view, so were always with parents on a smaller D class balcony and it was just fine.
