We were on the pre-inaugural sailing of the Diamond and I just fell in love with it so much I had to book the Riviera tour (we leave Oct. 30th).
First, we love the Princess atmosphere which has an upscale feel. teh cabins offer a lot of details in design that you don't see elsewhere (crown molding etc). The covered Conservatory pool is incredible, with high quality chaise lounges.
Finally, with personal choice dining, you have your choice of 4 restaurants to pick from -- this is what I fell in love with. Kuki penned an article about 'em just recently.
Finally, here are 53 photos of the ship I took when we were on her in March
