Al, what a WONDERFUL surprise - your wife will be thrilled! I think like you do - it will be hard to go back to a "normal" suite. We will find out this November, as we booked another Whisper cruise and had to book a midship verandah. They were already sold out of Silver Suites when we booked in early April! This category is, IMO, by FAR the best value out of all the "higher-end" suites.
Yes, we did dinner one night course by course in the suite. It was very nice - we just propped the door open and let the room service personnel come & go with each course. There was quite a bit of time between courses, but no worries. That gave us a chance to digest each course!
We didn't try to access the web via the TV, so I'm not sure about that one...
I just looked at your itinerary (because I DO want to be your next door neighbor - LOL!). Interestingly enough, we are doing almost that exact same 9-night itinerary this November - also called "Islands in the Sun" - the only difference is, we make a stop in Grenada in between St. Lucia and Barbados.
