I had a MK suite (one bedroom) over Thanksgiving. I would NOT do it again. I have stayed on the 12th floor MANY times over the past 10 yrs and that is where I would stay if I ever stayed at the CR again. It used to be our family's favorite resort, but that suite was so run down and scummy (black gunk in the tile grout, ceiling tiles caving in, ripped & stained wallpaper.....) I would NEVER do the 14th floor again. I felt totally ripped off and disappointed. The cms are wonderful and you would get the same concierge help on either floor. The food is basically the same except no evening appetizers and treats on the 12th. We basically only usually use the concierge food for bfast, anyway.
The 14th was a holiday splurge for us, but it was extremely disappointing.
The 12th floor is worth the money - the 14th floor - especially a $1200+/night suite is NOT. Just MHO, dont do it. I did not think the rooms on 12th floor were as poorly maintained as the suite we stayed in. Maybe we just got a bum room, I don't know - but I was not happy and I did let the concierge staff know. For a "contemporary" resort, we had an OLD microwave -never seen one that old, furniture that was showing it's age, a video player - no DVD, just not impressive......People have reported having the staff stock their fridge, special room keys, special turn down treats - we got NONE of those things.
I have also stayed in the Poly Hawaii concierge building. It was fine, but overall I would stay GF, BWI, YC/BC or even the Swan/Dolphin.
That horrid stay on the 14th floor has soured me on the CR. My kids still want to stay there - but my kids don't care about $$$$ or dirt.
Good luck with wherever you decide to stay. This was just my experience there and I know others have had great stays on the 14th floor. I really did used to LOVE the CR until that stay.
