Quite honestly I think it just comes with the age. My soon to be 2.5 yr use to sleep 8:00-8:30, just since the last time change he's changed from 8:30-6:30-7am....I tried limiting the nap time and cutting it out. He still soooo needs it still and didn't make a difference one bit on his wake up time. In fact he woke up 1.5hr earlier on those day...sigh :)
So far the only thing I found that got him to sleep in longer was putting him to bed EARLIER...Yes, I said earlier don't ask me why, but every one of those sleep books say earlier bedtimes= better sleep. But unfortunately it's just not practical in house to put him to bed at 6:30 or 7pm. So right now I am just making sure he gets a good long nap, and that's when I do the "my time". As it is today I put him down for his nap at 2 and its almost 6:00pm..ya a 4 hr nap...& the crazy thing is he'll still go down for bed at 8:30 or 9. I've tried waking him up from his naps and all too and it makes no difference on the sleeping in part.
You might have to play around with her schedule some, but maybe an earlier nap time, so she's up longer before bed would tire her out some, to get her to sleep in. But I don't know if you want to stop naps all together. Or go ahead and try it for a few days, doesn't hurt any, and see what works..Good luck this age is definitely a "fun" one :)
