I always used to stay at Deluxe resorts, and always got a good discount. The last time I stayed at the BWI, even with a discount, it was $300 a night, just for my DD and me. It was totally not worth it, and we stayed a couple of times at Pop after that. We enjoyed it more at Pop honestly! It didn't feel like we were throwing money away.
We did rent from an owner at AKL Kidani last spring break, though, and it was a very good rate (I think I paid $2,000 for the week for a one bedroom with two bathrooms, and it was all four of us so we had a bit more space). I didn't care for Kidani, though. The bus service was not as great, and I enjoy quick service food, so getting to the Mara was a total pain. Not interested in staying there again.
I doubt I'll stay at a Disney deluxe resort again, unless it's a very, very special trip. Now that my daughter is going to college next year, this coming spring break may be our last trip for a long time. We're booked at All Star Sports (again, just the two of us). It's still not cheap, even with a very tiny discount.
I'd love to go back to the Grand Floridian some day, but it's so not worth what they charge.
