My son is 3 and play would always win out over sleep no matter how tired he is, if he got a vote that is. Every day at naptime he walks to the window, pulls back the curtains and says, "Do you see? There are no more stars, there is no more moon, it's not bedtime!" But I know the sleep is necessary for him and for us when he gets so tired at the end of the day that he is impossible and we are frustrated.
If it IS that when she wakes up you are gone for the rest of the day until the next (for her I mean) I have an idea. What if you told her that when she woke up she would have a magic kiss. But she would have to go to sleep to get it. Then before you leave and after you get home at night, while she is sleeping, put on lipstick and leave a kiss on the back or palm of her hand. That way when she woke up she would know that you had been there while she was sleeping and loved on her. It would be a special thing between the two of you, like a ritual that lets you be a part of her waking up and going to bed, and it could provide her with assurance if that's what she's missing. If you don't want to do kisses, you could do heart stickers or something else like that.
If it's just fighting sleep, and you know she still needs the naps, you may just have to battle through it. Our son lets us know, loudly and effectively, his feelings about sleep, but he has to sleep anyway.
Hope this helps,
