I'm looking into getting a 3-bedroom room vs. 3 separate rooms for our party of 9. I am having trouble finding information on the 3-bedroom units. Are they just 3 hotel rooms linked together, or do they have their own, distinct floor plans? Are they the rooms usually held for DVC members and then rented out as hotel rooms when available (like they do in WDW)? What are the grand villas and how are they different? Thanks in advance.
