My daughter and son-in-law stayed there on a Friday and Saturday night before checking into Disney's Old Key West on our DVC points. My daughter said it was nice. Great for a basic, clean, good location room for a few nights. If you are doing the parks and running around, she said it was perfect. It's not a "resort" experience like a themed Disney hotel, but if you just need a basic place to stay, she thought it was fine. She requested parking lot side (away from the highway noise). She said the room was clean. She even sat at the pool one afternoon and enjoyed it. She said it was very convenient to Downtown Disney and restaurants, etc.
She liked the location so well that we just booked them a "getaway" week through Interval for Celebrity Resorts Lake Buena Vista in June (3 bedroom). I think Comfort Inn is 8442 Palm Parkway and Celebrity Resort is 8451 Palm Parkway. Definitely a nice location if you are not staying onsite at Disney.
