Well after much deliberation over the weekend I finally booked the 4 night Bahamian cruise on the Disney Dream for October 2011. 
I tried to book it direct with Disney but for some reason it wouldn't let me complete my booking so I booked it with Dreams Unlimited again. They had all my details from last time so didn't have to go through any lengthy form filling either.
One thing I have discovered though is that due to some abuse with the ship credits given by a travel agent, ( not Dreams Unlimited ) Disney have now reduced commision paid to travel agents on transferred bookings. therefore, if you book with Disney and transfer to DU, you won't get the full ship credit as if you booked it direct with DU in the first place.
Just waiting for Disney to hurry up with their hotel releases for next year now!
