No, not from the beach. The lodge itself blocks the fireworks. You can see the fireworks from SOME standard rooms of the North Wing at the lodge. In addition, if you go up to the 6th floor, and walk down the hallway, there are some windows that you can see the fireworks out of (at the corners of the hallways).
If you are booked in the standard room category (my favorite, simply because of this ability to see the fireworks), just request a 5th or 6th floor room in the North Wing, facing the Magic Kingdom. You will have a PERFECT fireworks view from your beds every night. I've been lucky enough to have it on all three of my stays at WL.
