For a 2 bedroom it will probably be a condo or it will be a 3 bedroom townhome - slightly bigger but may have a few more little extras like private hot-tub or splash pool.
Personally we like areas off Highway 192 and the new resorts/townhomes but everyone is looking for something different Have a look through the Hotels and accommodations reviews section on the DIS for some ideas of condos/townhomes you may like. Then just post up any questions you may have
my preferences to be close to Disney, if not a DVC villa, then Bonnet Creek. a little further offsite, I loved Marriott Grande Vista and Marriott Cypress Harbour. The kids, DD5 and DS6 preferred Grande Vista.
yes. Condo's will have a community pool and other resort facilities, townhomes will possibly have a plunge pool/and or spa and they will have community pool as well and villas will have (more than likely) a private pool (and often a spa)
If you're looking at individually owned condos or townhomes, then also consider 3 bedroom places as they typically don't cost much if any more than the 2 bedroom ones, and there are many more to choose from.
