No, there are no home rentals on property. Plenty off site, though. On property your choices would be
- regular resort rooms (at least 2).
- a family suite at AoA or ASMusic. These would be cramped with 6 adults.
- a cabin at Ft Wilderness. Also likely cramped.
- a 2 bedroom villa at one of the Disney DVC resorts. Pricey. Very Pricey.
Also technically on property, but not owned by Disney (so no guest benefits) is Bonnet Creek . They have condos to rent. Haven't stayed there, so can't comment on them).
- The family suites at AoA and ASMusic would indeed be cramped for a family of 6, unless the master bedroom includes another pullout chair and I don't think it does. Both the pull out couch and the pullout table in AoA are roughly the size of double beds. If the OP has members of his party that are larger than average, it can be kind of tight. Plus, the Value suites are themed more for families with young children, and the youngest in his party is 23. If they're among the very young at heart, or if they intend to be "park commandos" - spending little time at the resort, just hitting the parks from dawn until it's time to crash at night, the value suites might be great. But for 6 adults I'd think the lack of amenities in the resorts, the lack of any table service restaurants and the tight quarters might make it less than enjoyable. But everyone's mileage may vary.
- The cabins at Fort WIlderness are smaller than the value suites, and only 1 bathroom for 6 people (with [possibly] nearby comfort stations if necessary) but you're also getting a full deck with a charcoal grill outside, plus a full kitchen inside, if the OP wants to have some "home cooked" meals while on vacation whether it's for comfort or to save some money. Also, the sleeping accommodations include a master bedroom with a queen sized bed AND bunk beds. If the party of 6 includes 3 couples versus all siblings, not only is one couple getting the short straw, but the most privacy will ironically be in the living room area with the pull out.
- If the OP wants to ideally stay on Disney property in a single "home" for all 6, then probably the most economical approach would be to check out David's DVC rentals. For a week throughout most of March, in the $4300-4500 range you can find 2BR units that will give you a king sized bed in a master bedroom, a 2nd bedroom with 2 queen sized beds (as well as a sleeper sofa) and at least 2 bathrooms, in Saratoga Springs, Old Key West, and the Standard View categories at both Boardwalk and Animal Kingdom Villas (and the Animal Kingdom Villas will include 3 bathrooms as opposed to 2). For chucks and giggles I looked up the first full week in March on travelocity, both Old Key West and Saratoga Springs show availability but the price for the room alone would be in the upper 8K range. There might be promotions down the road that will cut the price down significantly, but not for now. And of course if the party of 6 could be split up into 2 rooms, renting DVC points and staying in 2 studio suites would save even more.
- the same Travelocity search for the same week shows availability at Bonnet Creek for less than 3 grand. The tradeoffs - you can't use Disney Magical Express to and from airport if that's something you wanted (but the $ you save could go towards a a private car service), the hotel has its own shuttle service to/from parks that might not be as good as Disney's onsite transportation (but WDW transportation isn't always so great either) and you won't have room-charging privileges. But if the OP's group doesn't want to be steeped in all things Disney 24/7 this might be an attractive compromise. Lots of onsite amenities including its own lazy river and miniature golf course.
