Cheshire Figment, they do consider the Swan and Dolphin to be the same as staying at a Disney Resort as far as free parking at the theme parks. In fact, the only things that are different for the Swan Dolphin is that you can't charge at the parks or DTD with your room key and you have to show your room key to get free parking since they don't give you a piece of paper to keep on the dash of the car.
But e-nights, magic morning, delivery of packages to the resort, length of stay passes and access to all Disney transportation is exactly the same.
Oh, and I agree with you about tipping valet. We always tip both when we drop off and pick up since the tips went way down once they instituted the charge for valet parking. And we can valet park for free since we have a handicap sticker at any of the deluxe resorts on property, so we end up tipping a fair amount(smile).
