For us and for some others that have posted here, MK view makes or breaks the CR. Problem with Concierge is that you cannot guarantee MK view so for us, this is always a deal breaker. Our preference is to get MK view and as far as breakfast etc. goes, use the food+fun center below or room service.
What do you get out of MK view? The magic of the MK and the castle from your room. On a nice day, just sit out the balcony - see all the boats, monorails, resorts, MK - at sunset and at night you see all the lights. The castle changes colors. You can see fireworks from your room. The other Bayview is nice as well but you lose all of this.
