We actually stayed at Silver Lake Resort on our first two trips to Orlando, and really liked it. If you take Sherbeth Rd., which is right next to the SLR, you can take that back road all the way in to WDW without hitting any traffic lights until the one right outside AKL.
I guess you could take back roads all the way to UO instead of I-4, but it would probably take longer. The SLR is on the opposite side of WDW from UO.
