An August time frame just so your aware would be hot at Disneyland, and the end of August to Mid Sept the hottest time of the year usually with a hot wind that blows. From your other post, it appeared that may be an issue for you .
You would also want to avoid very late August as August 30th- Sept 2 is a big Holiday weekend, Labor Day weekend, and also is a Half Marathon held at Disneyland, so that weekend will be extremely busy at Disneyland.
There are really not any Condos or time shares in very close walking distance to Disneyland. Most would be about 20 min to actually walk in. There are some Condos on Walnut/Magic way area that are about a 10 min walk to the Mickey and Friends parking lot free tram that will take you into Disneyland from there, and are about a 20 min walk to the Turnstiles. But, there is not much around that area as its on the opposite side of Disneyland.
There would also be the WorldMark time shares, also about a 20 min walk with Art Shuttle service near them. And Peacock Suites which is also about a 20 min walk with Art shuttle.
Can you give us a budget per night? August is the busy season, so prices are at thier highest.
Plenty of standard Motels which are the closest across the street from the Disneyland Main Entrance. Most of those will have a small fridge and microwave in the room.
But it sounds like you may want something nicer?
You can look at the Fairfield Inn which is about an 8 min walk across the street to the Turnstiles. Or Howard Johnsons about an 11 min walk, and has Art Shuttle.
Residence Inn Maingate...... may be what you are looking for if its in your budget since it has large rooms, and full kitchens, free full breakfast and some weeknight light suppers. Its layed out like a low rise Condo like setting. Its about a 15 min walk to the actual Turnstiles that go into either Park, and has Art Shuttle service for a small fee per person available if you dont want to walk.
