Hey C....
I too have a 2 1/2 year old "princess". I am still in the process of starting the potty training...but had a bad run in with a serious case of constipation...which created bad thoughts with potty training, so have backed off for a few days. I have potty trained our son however, and got tons of advice.
I think the biggest thing that worked, was to take diapers and pull ups completley away, except for naps/night time. Just have her wear underwear all day long. You'll want to get LOTS for accidents, but it works...and FAST! You'll probably have a rough first couple of days, but then it should start getting better.
One thing we do is set an egg timer for an hour, and have her try every hour...that's why it's good to do it during a time when you will be home for several days in a row.
We also pretend the princesses on her panties are talking to her, which she thinks is so much fun, and they say things like "please don't let us get wet" "we don't want pee pee on us" and she'll try her hardest not to do it.
Hopefully that helps! Let me know if you have any other questions, and how it goes! :)
