I'm scared too... I just keep repeating to myself the WISH motto.. that has really kept me encouraged... Dead Last Finish is better then Did Not Finish is much greater then Did Not Start. Dh is really discouraging because he feels that if you don't try to run your hardest you aren't really accomplishing anything.. I'm going at this to be able to say I finished... I'm a half-marathoner and I'm going to have FUN!!! You will be running with 1299 of your new closest friends LOL.
The WISH motto has gotten me through many a race as well. The fact that you have gotten to the point of being ready to start this race is a huge accomplishment.
The thing about running your hardest is...well, there are a few things:
It takes practice to be able to push yourself to the max in a race while still being able to finish.
A sprint is not an appropriate approach for a longer distance race. Different peoples "max" is just....different.
Just because my pace is slower, doesn't necessarily mean I'm working less hard than the people who finish ahead of me.
Just because someone walks some or all of a race doesn't mean they are taking it easy! Far from it. I have seen the last finisher of quite a few races and I daresay in almost every case, the person who comes in last is working just as hard for that finish as anyone else, possibly more than many, and for a longer period of time.
I keep telling myself, if I have to, I will CRAWL across that finish line! It might sound a little corny, but I'm putting a bunch of uplifting types of songs on my ipod to listen to at the end. For example, the Coldplay song Viva La Vida really gets me going when I feel crappy.
Oooh, I love Viva La Vida on my shuffle when times are tough! My other current favorites when times are tough include:
The Middle by Jimmy Eat World.
She's Got the Look
Mr. Blue sky - a dance remix
The Lonely Goatherd by Lora Munro (I like the remix)
and (drumroll)
The Hamster Dance
One final thought on racing at Disney - Racing at Disney is different from any other race I've ever done. The fact that people stop - flat out STOP in the middle of a race for pictures with characters - stopping in races is just not done, generally, but people at all paces stop for pictures in these events. A friend of mine also ran the half in January and he had a camera with him but did not stop for a single picture. I offered to take his picture with the Goofy bilboards but he turned me down!! He aspires to be a more serious racer and he just doesn't stop during a race - BUT after we got home, he looked at my photos and said he actually regretted not stopping for any himself.
Regarding the last three miles - yes, they can be very challenging, but you have the knowledge that you have already completed 10. When I got to that point in my frist half marathon, my feet were really tired. I had had an injury and had not gotten all my miles in training. So yes, my feet hurt. At that point, though, the distance remaining is a fraction of what you've already accomplished!
As for taking a cab vs. driving yourself, I'm going to say that if you have a car, probably it makes more sense to drive. If you are thinking of renting a car for this one thing, taking a cab is fine, too and less expensive. Once nice thing about cabbing it is if you are nervous pre-race, you won't have to stress about getting there on time/getting lost/remembering where you parked. Nice thing about driving yourself, though, is you don't have to check your bag.
I'll wear my WISH nametag to the meet - is anyone bringing sticky nametags to POR? I could probably bring some if that would help. It's nice to be able to see people's usernames and real names together with faces.
He still insists he could do it for a few miles.... and i told him, "Maybe you can -- but, you won't be able to walk after!" 
Reading the last posts, I feel we are all going through the same emotions. I keep saying, yes, that's exactly how I feel right now too. Critical husband, personal doubts, nerves, etc., they are all surfacing. But we must all remember, we can do this; we will do this; and we all should be proud of ourselves (at least that's what I've been repeating to myself)
