We(4 of us) stayed in an 11 the first time we sailed, then DH & I went back alone in a 10(SPHR). IMO, the SPHR was so worth going up 1 category. However if I only could have gotten a regular cat 10 with no view, I dont think I would have bothered. We really liked the location of our 11(on deck 5) and the split bath in the 10 wasnt really that much of an advantage to us. I believe the extra space in the room is only because of the split bath so the room itself isnt much bigger than an 11.
