Just wanted to thank everyone who offered advice and opinions.
We arrived both ways with no missed flights or lost luggage. It was a very long trip home-starting a 7am and getting home this morning at 1:30am (ferry/plane/plane/plane car.
I always keep a journal and will post a trip report when I am functioning on more than 2 hours sleep. I will make a few brief comments.

Mariner's Hotel on St. Vincent was fine, but did not look as nice as brochure. Staff very friendly and helpful. Not much land here, so the grounds and landscaping were small. Convienient spot to walk to nearby restaurants. Internet Cafe free for guests, a great perk.
Kingsville Apartments on Bequia--wow!! I was a bit hesitant on booking at this place, the website made the apartments look nice, but sometimes that is not the case. The only negative thing I can say about Kingsville --very hot in the day even with windows open(on a sunny day). They have a/c in bedrooms only which they ask you only use when you are in the bedroom. Beautiful, colorful and great, new condition furnishings. The tropical landscaping absolutely gorgeous. Quiet location very quick walk to beach (and yes, we could see and hear the water from our apartment). Other negative, solar powered hot water. We had hot water the first day and the next three days none(cloudy day/rainy day/mostly cloudy day). It is very hard to shave your legs when you have goosebumps. I would highly recommend Kingsville, unless you require a/c in all rooms at all hours.
People at Grantley Adams Airport in Barbados super friendly, especially at the Caribbean Star desk.
Wonderful trip aboard Passion to Tobago Cays, with the exception of the weather that decided to pour upon our arrival at the Cays (quite disappointed, as I have been waiting for that trip for years). Captain a fun and entertaining guy.
I would also recommend a trip to the Falls of Baliene with Hal Daize of SeaBreeze Nature tours. He was great. Very eager to please and to make sure we were enjoying our trip and answering any questions, passing on lots of history.
Got ripped off I believe at the Botanical Gardens and possibly Fort. I forgot my notes on what the guide book said. We paid $20 US for the Fort Charlotte Tour for two adults and one kid. At the Botanical Gardens, we paid $20 again. I made the mistake of asking what I owed him and he gave me the story that most people pay $20 US, but that we could give more or less. I was not that impressed with the Botanical Gardens they were nice, but I think Romney Manor on St. Kitts was is far more superior.
Great cab drivers Elvis Miles on Stl Vincent and Roland (Fummy) on Bequia--both guys very dependable, friendly and always on time as requested.
Airport on St. Vincent upon departure very very slow.
Weather cloudy first day, few sprinkles here and there with lots of rain every night. Only rained out one whole day, all day.

Trip report coming soon
