I have never worked for but here's some advice:
Item#1: It's not about you or Disney. It's about the guest. Guest experience is #1, #2, #3 priority. If you've had magical experiences at WDW you WANT to share it and spread it.
The above is the Quote of the day!
My son did the Spring Advantage 2012 - got in first time. My daughter was rejected her Freshman year, but, got accepted 2 days after her interview this year (Spring Advantage 2013). So, there is no blacklist if you get rejected!
In this - or any interview - there are 3 key things that the interviewer wants to determine: 1) Can they do the job? 2) Can they get along with co-workers and 3) Can they deal with customers? And, I think if you recall your interview every question dealt with one of the above 3 topics!
You don't have to hide the fact you love Disney - but - they know that you love attending Disney as a guest! Being a CM is much different! 1000% times different! It matters extremely little in their decision factor! No interviewer is going to say: "Ohhh - you Love Disney - my god, your for us - what position do you want?".
Simply put - your love for Disney and WDW has 0% bearing on your ability to do a job. Every kid who applies want to do this cause they love Disney! Ohhhh, so, you love Disney more? What does that count for? You might say,
"Well, I love all things Disney and love the atmosphere and that was a driving force in my reason for applying. On the flip side, I realize I am trading roll's - I am no longer the Guest but the CM! I have always respected so many CM's I have met in the past - their enthusiasm and dedication was apparent to me. I have used that experience and applied it to all of my Volunteer positions when dealing with customers! So, while not employed by WDW, I have been a CM for a long time."
Trust me - my daughters love for WDW has not shown through this week after getting back-to-back 12.5 hour shifts at the Food and Wine Festival! A day off - then two more 12 hour shifts. She's not happy - but - does her job and with a smile.
My daughter also wanted to go through the program with ZERO strikes! One day she was by herself selling drinks / chicken legs in Epcot and gave a customer change for 21.38. The guy put the change in his pocket, then, brought it back out and said - you only gave me 1.38 in change. She said - no - I counted it out in front of you - I gave you a 20, a 1 and .38.
She was forced to call a Supervisor (via Walkie Talkie) - who came out and talked to the guy: He finally reached in to the till and gave him 20! The supervisor asked her later - "You sure you gave him the right change?" She said - 100% - but - we will find out when we balance the till. Her till ended up 20 short after 200+ transactions. Anyways, she got a strike for being under. That is how the real world works - life is not fair, nor, is Disney Management.
Anyways - a lesson learned and she has devised a new method when handing back big bills to make sure some other con-artist does not rip her off.
My thoughts:

Keep your head up. Didn't work this year! Keep trying.

Study! I know there are dozens of posts out here on Questions - spend time reviewing them and get your answers down pat prior to the interview. I worked with my son and two of his friends reviewing questions and potential answers. We created 3 X 5 cards that they wrote up - and had them spread out on the table before they took the interview. Both of them got in - a similar system was conveyed to other folks - they two got in first try!

You may want to get a part-time job! The better ones would include some type of customer interaction.
On the working thing, I agree with others that many get in with no work experience. But, if there were two spots left open and you and another candidate had equal scores on the interview - but - your competitor had previous work experience: Be honest, who would you hire?
Volunteer work is as good as work experience. Just: Get yourself dealing with customers and get written referrals and offer them to Disney! If you are a volunteer and cleaning out Pet Cages - then - explain to your supervisor how important it is for you to get lot's of customer interaction. If they say no - find another volunteer position!
The driving thing - WDW does not need to know that! Ton's of kids down there ahd don't drive. Trust me - from the apartments to WDW is some of the worst traffic in the world. Have driven for 30 years - don't like that driving! And, I have driven in New York, Paris, London and Amsterdam.
One last thought - My son told me he had talked to folks who had got in after being originally rejected - they learned that their initial preferences were way too limited: Character Performer, Boutique, etc., etc. My son felt your odd's increased if you chose Merchandise or Food - as there are 1000's of jobs in those categories.
Good luck - you will get in eventually!
