Hi again Barry,
I've seen a couple of accommodation/dive packages for Barbados on padi.com that you may want to check out and the prices look decent.
Scuba Diving Vacations & Trips - PADI Scuba Diving Training Organization
I myself use vrbo.com for a vacation rental. I can provide you with specific links if a private vacation rental is something that interests you. However, these typically book up to a year in advance as they see many returning visitors. I think it says something about a place when you meet folks from all over the world that choose the same vacation spot year after year, which is what I encounter every visit I make to the island.
As for hotels, I have friends that enjoy staying at the Coconut Court when they go to the island. Other folks I have met while diving like staying at the Hilton, which is where Dive Barbados Blue is located, so it's extremely convenient for diving and it is located on a beautiful beach (although I've never encountered a beach that isn't beautiful there!). There is also a new AI called SoCo that I heard positive reviews from folks I met while there this past November/December. Both the Coconut Court and SoCo are located close to the south coast boardwalk which is convenient for restaurants, shops, etc. If you are interested in staying in an area with more bars and nightlife then you may want to look into hotels located in St Lawrence Gap. I myself go for relaxation and diving, so I can't give you any info on hotels located in the Gap.
I'm a big fan of Barbados and it's people. I have had nothing but positive experiences there. If you go, I hope you thoroughly enjoy yourself. If you want some suggestions for restaurants, I'd be happy to give you my $0.02 on that as well!
