Differences between Cloud/Wind & Shadow/Whisper

My wife and I have sailed only on the Shadow and Whisper on our two cruises with Silversea. While looking for 2006 cruises, I noticed a number of cruises that I wouldn't mind taking which were on either the Cloud or Wind. This got me to wondering as to what we should expect to be different (other than the price of a Silver suite and the number of people on board) between the smaller Cloud and Wind and larger Shadow and Whisper. Could someone please enlighten me?

I've only sailed the wind and cloud and they are both lovely ships. From what I understand the cabins on the smaller ships are a bit smaller, mostly in the bathroom and there might be one or two less public rooms, but otherwise comparable. Many actually prefer the smaller ship.

We've been on the Wind and Whisper...the biggest differences we noticed:

Whisper bathrooms have double vanity and a shower stall separate from the tub. Wind has single vanity and shower/tub combo.

Wind balcony doors swing out; Whisper has sliders, which IMO, give you better use of the space on the balcony. Oh, and I think the balconies on the Whisper are slightly bigger than the Wind.

The casino on the Wind is quite a bit bigger than the Whisper. We felt cramped in the Whisper's casino. However, this may be due to the fact that there is a bar adjacent. The Wind doesn't have a separate bar dedicated to the casino - it adjoins and "shares" with the main bar.

Both ships are fabulous!

one more thing I just remembered - the Wind's gym is WAY better than the Whisper's. I didn't spend any time in there (LOL) but my husband did....
