Here is how I finally beat that part: Start by standing behind the ferris wheel and looking at where the enemies will come from. Then turn right and you should see a building with bumper cars. Go to the point where the building ends and camp right there with your sniper ans start taking out the enemies. If a grenade gets close you should have ample room to get out of the way. You shouldn't have to worry about enemies rushing your position to much. When the helicopter arrives kills the enemies(if any) that are by ferris wheel, and make a dash for the Captain. Once you have him go right to the heli. You can take a lot more damage when you're carrying him. Took me five tries using this method until i beat it.
I managed to exploit a glitch...first, when the helis come in to drop off people, run to the old swimming pool building all the way to the back. Then take a left and go until you hit the chain link fence, and there's a small hallway that leads nowhere. This prevents the dozens and dozens of enemies from spawning (apparently if you get too close to their spawn point they don't spawn at all), while you can pick off the people that were left in the middle. Still difficult, but much less so.
