Heard some not so good things about the La Quinta Lakeside, but its hard to find a hotel that DOESNT have some bad things said against it.
One of our favourite areas to stay is Lake Buena Vista. There is the Sheraton Safari which is a nice hotel, very close to the attractions. The Comfort Inn & Suites offers good value in a great spot.
Places I would avoid, would be any hotels that are too far east of the I-4 on the 192. This is a very crumby area and I wouldnt want to stay here. We also dont like the "Maingate" area, as the hotels here look very sub standard.
There is a split opinion about I-Drive - some find it noisy and tacky whilst others find it a brilliant central spot to stay. Personally, I love the Plaza end, which is greener, quieter and nicer than the more noisy northern end.
Maybe do a bit of research, pick say 4 hotels you like the sound of and then make another post.
Have fun planning!
