Potty Party??!?

So, I've been trying really hard to fully potty train Zander. He is really good, some days. But, he will not go #2 on the potty and he has days where he totally fights it & wants nothing to do with it. I've tried many bribes, but they only work for a few hours. He's interested for a little while, than it just wears off. While I was shopping at Walmart, yesterday, I found a book in the toddler section titled, "Potty Training Your Child in Just One Day." I bought it. And read it in one day. So know, I'm debating whether or not to try this "one day" process. According to the book, you throw a big "Potty Party," celebrating the departure of diapers and the introduction of "Big Boy Pants." To do this, you wake up in the morning and give your child a wrapped gift of doll. You spend the morning hours having your child teach the doll how to go potty, and reward the doll for sitting on the potty and for going pee or poop on the potty. In between this time, you watch videos, read books, and play games and activities that are associated with potty training. After lunch, you give them another wrapped gift of underwear. Now, it's their turn. They have to go practice sitting on the potty and using it. Of course, you are supposed to give rewards and lots of praise. They should catch on by this time and start using the potty. At about 6pm, you end the party with family and friends coming over to help throw away the diapers and open presents in celebration of your child becoming a "big boy (or girl)."

So, what do you think of this process?? There is a lot of expense involved, you have to buy a doll, new underwear, gifts (although the can be simple small things), party decorations, treats, and videos and books. Also you are supposed to do this with only you and the child at home. I wonder if anyone has ever done this and if it really works. So, if you have any thoughts please leave them here for me to read. Like I said, I'm not sure if I really want to do this or not.
