What about putting a gate across her doorway so she can't get out even if she does get up?
Something that seems to help my DD is to appeal to her sense of being "big" and talking about how Olivia (for example, the pig on TV and in books) goes to bed like a big girl. See how her mom turns off the light? I also tuck DD in with all her blankets, her dolls, and her sippy cup. It used to be that she'd wake up, feel thirsty and cry for me. I am happy to use a sippy of water in her bed if that helps us sleep.
Maybe you can talk to your DD about how if she wakes up, she needs to go back to bed like a big girl? If you do wake up, you can say, "What do you need to do?" and any night she doesn't wake you, praise her in the morning.
