the best place to go is to go to the bridge next to the Ballys Hotel Ceasars Palace. You are up higher and not in the crowd of crazy drunks below.
Depending on how close you want to be, Stratosphere has fireworks this year as well as several Strip casinos. And I believe Red Rock will have some again this year. To see them all I would go to Desert Breeze Park. I think Sunset Park is too low in the valley with too many objects in the way as well as street and park lights.
Since they will be shot from the top of the hotels this year Sunset Park would be a good place to see them. As long as you can see the strip you will be able to see the fireworks which is just about anywhere in the valley.
I say any distance you see every casino on the strip, but the fireworks don t go up so high in the sky so it might not be a smart idea to go to a far part of vegas to watch. Avoiding the strip is your best bet, crazy down there.
I would deff. say if you go up by red rock casino you can see all the valley the only one you cannot see is going to be the sante fe because of lone mountain is in the way but it s a great place...
