We had friends who have a timeshare at Vistana, which is beautiful, & they had told us we could have a room for our family, so Vistana confirmed that.. About a week before we were to leave they called and said we would be staying at their sister resort, the Parc Corniche. My mother and I got there first, we drove down, so we checked in. They brought us to our room on the third floor and no one offered to help with the luggage but when they opened the door there was a family in the room already! We had to go back to the office and they brought us to our next room which was all the way at the back of the resort looking at the woods and it wasn't a nice view. The pool was closed and they told us they had a nice breakfast area but that turned out to be a walk up window that you could get snacks in.
When we actually got in the room, it was not the cleanest place. When my sister got there with her kids, we had pulled out the sofa so they could get settled in bed, and there were potato chips in the bed!! There were dead bugs in the corners of the rooms and it was just not pleasant & the refridgerator smelled bad too. We did complain but they said they had no more rooms available and definitely not at Vistana. We did get a small discount on the rooms when we left but it wasn't much from what I remember.
Just a side note, this was in 1999 and it was our first trip with the whole family and it was also the last trip my mother was ever able to take to Disney, she passed away in 2002. It was also the ONLY time any of us had stayed off property.
The other things that bothered us were having to drive in and out of the parks everyday and paying to park. It was just such and inconvenience to have to get to the car then drive to the hotel late at night, not to mention spending extra money on gas. I would much rather wait for a bus and just go right to the room, while carrying our sleeping kids instead of having to buckle them in the car and waking them up. I know someone mentioned taking a shuttle but then you have to be on someone else's schedule and if you miss the shuttle then you have to pay for a cab, so then what's the point of saving money!
Sorry for the long story but I had to just fill you in on a little of it.
By the way, another thing was, anytime we bought anything in the parks, we had to carry it around all day and to the car and then into the rooms. If you stay on property, you can have whatever you buy sent to your resort. The only thing you have to do is pick it up the next day in the store in your resort and bring it to your room! This is probably my favorite perk about staying on property!
Not sure if this would be an option for you but we drive down a lot to also save money. Not sure how that would be with the gas prices now but if one of you has a decent car, take that down and take turns driving so you don't have to get a hotel room. It usually takes us 18-20 hours straight through. My sister and I are doing this again in October for my 40th birthday!
