Would she be open to renting a car and driving? The place we stayed was extremely easy to get to/from the parks. Plus, with a car, we could just hop in and go whenever we wanted, instead of waiting for the bus/monorail etc... I mean, it's not "as" convenient as staying on site in a way, no, but we didn't find it hard at all. We were 15-25 minutes driving time away from the parks - and that was in rush hour traffic during busy season, and it was a very easy drive, well marked and very straightforward (this coming from my husband who DESPISES city driving, lol). We did afternoon breaks a couple times, as well. We stayed in Glenbrook Resort, in a home owned by a Canadian, so not only did she give us a deal on her rack rate, but then also offered it to us in Canadian dollars! It was an excellent place, very clean, secure neighborhood, 4 bedroom house with a games room and private 24' pool - was only $100 CDN a night.
However, if you don't want to drive, then Windsor Hills is another rental resort that offers shuttle service, it's a bit closer, they offer everything from 2-bedroom condos, townhouses with a private splash pool or private houses with 20' private pools with I think 4-6 bedrooms. Then I know there's several other resorts (both condo rental resorts, hotel resorts etc) in the area that offer shuttle service. But for us two of the biggest savings were a) the cost of our lodging and b) being able to cook our own meals.
