refusing naps

so my two year old is now refusing naps. she'll scream, yell, whine and cry until I come get her. I'm at my wits end. I cant drop the nap yet because if I do, she gets so so so whiny and cries from 5pm on. what do I do? do I let her "cry it out"? I feel bad when I do it but I'm also a push over when it comes to her. what do I do ladies?! :/
