Disney Dolphin Hotel

It is pretty hard to find accurate information about what the Disney Dolphin hotel includes. 
Let me summarize based on my experience.

Parking - Includes Parking fees for the Disney Park

• Includes parking at the Disney parks.  Staying at a Disney resort provides free parking at the parks, but with the Dolphin and Swan, it's hard to tell what was included, and what wasn't since there are some exclusions on these 2 properties.  
• I thought that maybe parking at the Dolphin for the $20+ will include parking at the Disney parks.  But when entering the Disney parks, the people at the gate will accept the Dolphin room key card.  The key card includes the guest's name and dates of stay.  But there is no scanning system.  The parking attendant just looks at the card.
• More interestingly, the room card doesn't state if you parked at the Dolphin for the $20+ bucks.  But I suppose if you are showing up in a car/van with a Dolphin room card for the dates specified, then it is assumed that you've parked your car at the Dolphin..... otherwise, where else would be parking the car when you're at the hotel?

Taking the Ferry

• This is by far the best way of getting to Hollywood Studios.  We parked our van to Hollywood Studios the first day, thinking there wasn't going to be much of a difference.
