Besides the cabin being much larger, like double the size , the SY's have a double sink, 2 medicine cabinets and a separate shower stall in the bathroom. There is also more closet and drawer space and the verandahs are larger.
they also have a jacuzzi tub/shower combo along with the separate shower, larger verandah, larger room--in the VA,VB, etc it is difficult for two people to pass at the same time at the foot of the bed--not so in the SY/SS/SZ. Have had both and don't plan on going back to the V's again...
