December 2005, DH and I took my MIL to WDW for the first time. We decided for the first week, we would stay onsite and the second week we would get a rental.
For our onsite stay, we wanted my MIL to have her own room, so the best deal I could get was 2 rooms at POP Century, with the AP rate of $49/night, each. So, that cost us approximately $770 for the week.
For the rental stay, we got a four bedroom/3 bath home with pool and hot tub. I know. Four bedrooms for 3 people is a lot. But, it was in a location we wanted. Including pool heat and taxes, we paid approx. $815 for the week.
We never use Disney transportation. The rental car cost was approx. $250 for the two weeks.
So, for an additional $45 we got 2 more bedrooms and 1 more bathroom. We got our own pool/hot tub, washer/dryer, DVD player with movies, 2 car garage, kitchen with all the amenities, BBQ, a crib, high chair, a ton of space, and peace and quiet.
The rental homes bedrooms and bathrooms were much larger than the resort rooms. The rental was in the Sanctuary at West Haven community, which is a gated community, near Champions Gate golf resort. Which is about 15 minutes from Disney.
So, even for my small family, the vacation rental was money well spent. I would definitely do it again and would highly recommend it for others as well.
