Just passed Connie's challange to get through park in stealth. I managed to pass first screen by simply waiting. I noticed that top girl is moving slightly faster that bottom one so you can wait them to align in the way so when top girl is turning right to start moving, bottom one should pass right tree of trees block on top of her. This way you will have time to go and slip between trees to the left if you start moving the moment top girl will go right. To make it faster, you can go back to where you came from to the point when connie will say smth like "I can't go there" and just press and hold down arrow and Enter. This way dialog box will speed up girls from time to time. I think it takes a few minutes
