I had exactly the same thing going on a few weeks ago with my DD who turns 3 on Tuesday. I tried dragging her to the potty every 15 minutes, hour, two hours, etc. Didn't work. She just wasn't uncomfortable enough wet. I finally just let her have the accidents. I'd say a week of accidents and then she really started hating being wet and wanting to change clothes instantly. At that point, I picked up Curious George undies and we talked about keeping Curious George dry. Seems to have worked. She's dry all day with occasional accident right after nap according to daycare.
