From an entirely frugal perspective (classroom teacher here):
Buy a legacy 2 bedroom lock-off Marriott week at a low maintenance fee resort (Grand Chateau or Grande Vista) for a purchase price of $3,000 resale, lock off the room and trade into SSR and OKW every year for about $1300-$1350 a week for a 1 bedroom (maintenance fees + exchange fees). There are plenty of deposits just sitting there for the taking (in the picture below). The same unit using SSR points costs about $2500 a week when you factor in purchase price + maintenance fees.

Stay 1 week at SSR or OKW in the 1 bedroom and trade the studio side for a 2 bedroom in any of the Marriott Orlando locations for an upgrade fee of $198 plus $164 exchange fee. The Palms resorts (Royal/Sabal/Imperial) have access to the World Center hotel literally 2 minutes from WDW property and it has 3 body slides, 3 tube slides and a lazy river in its pool complex. If you only want 1 week a year then buy a every other year deed and alternate between a DVC and a Marriott stay.
DVC is a luxury purchase and makes 0 mathematical sense to buy over other timeshare systems. You're going to pay rediculous prices just for the brand. If the price is worth it for you, then go for it. I don't find it worth it, so I only own 50 DVC points to use in addition to my other ownerships that make much more financial sense.
