Of the ones you've listed the only one I've stayed at is Del Sol. The location was great and the room was spacious (we were put in a multi-room suite despite just having a reservation for a standard room), but it was definitely just a motel room. Nothing really noteworthy about it. But that's what we wanted, an affordable motel room with a great location. From what I've heard, that's basically what you get with any of those motels right across the street. The only thing I remember not liking about it is that we were not allowed to leave our car there after checkout even after we offered to pay for an extra day of parking because they have capacity issues. So on checkout day instead of being able to skip across the street to the parks we had to go re-park at Toy Story. But I wouldn't be surprised if the other motels in the vicinity have the same rule since parking space is so limited around there.
When I start to plan a trip, I basically make a choice if we're going to focus on location or quality. If we're going to stay at a motel across the street we don't plan on using the pool or hanging out in the room, so basically price is the deciding factor. If we want a more leisurely trip we stay somewhere nicer but farther away, and just do partial days in the parks.
