Picking up on the reference to renting DVC points, for those not interested in buying a complete package with the free dinning then as Wanye states this is normally the cheapest option for a stay at Animal Kingdom Lodge and possibly at any of the other DVC Resorts at Aulani Villas, Bay Lake Tower, Beach Club, Grand Californian, Boardwalk, Hilton Head, Old Key West, Saratoga Springs, Vero Beach and Wilderness Lodge Villas.
The cheapest times of the year for renting is Jan , Sept and Dec 1-14 followed by Oct, Nov 1-20, 24-30 and Dec 15-23.
For a week in October starting Sat 25th you will need to rent 116 points for a Savanna View studio, renting normally varies between $10 and $13 a point, so for this week the cost could be between $1,160 and $1,508 (£774-£1,005 at $1.50 to the £1.00).
A Standard View studio at either Jambo House or Kidani Village AKL for that week is slightly cheaper at 88 points, so between $880 and $1,144 (£587-£762).
While a July stay in a Standard View studio would be 116 points, so a similar cost to the Savanna View studio as above in October.
Renting at most times of the year therefore can be much cheaper but it is less flexible as normally there's no option to cancel for a refund and or change dates.
