Hello, Villas at Island Club are basic but roomy option for you...I looked at the Emerald Island link and before you choose I would compare extras such as king vs queen beds, TV/VCR in all bedrooms, how close to the swimming pool if you want to swim lot...Emerald Island will be about 2-3 minutes closer to Disney...
Villas at Island Club using Black Lake Road is very close to Disney via the Animal Kingdom entrance...The V at IC have a nice walk in shower in the master bedroom...It definately is a basic condo vs. the really fancy ones that are time shares...The furniture in the Em Island condo shown is very basic...
Good Luck...I think either would be very acceptable to you and location of each one is excellent..
