How is Disney World end of May and beginning of June?

I had just booked a trip with my fianc� for next year, May 26th to June 9th. I know we are going to get there on memorial day weekend but does anyone know how the crowds are and how the weather is? Also, we booked contemporary hotel with a magic kingdom view. Has anyone stayed in the MK view room? If so, how is it? Thanks everyone.
