There is the 4th floor observation deck at the Contemporary, beach at the Polynesian, marina at the Grand Floridian for the Magic Kingdom Monorail Resorts. I am not sure where you could see the fireworks from Epcot at the Epcot Resorts. However since July 4th is a very busy holiday at WDW, it might be a hard time trying to visit any of these these Resorts without ADR's that night since they would restrict access and only let in guests staying there and guests with ADR's. Even if you are thinking about taking the bus from CSR to the Magic Kingdom and going to one of the Magic Kingdom Resorts, it might not be running because the Magic Kingdom might be in one of their closing stages. Here is a list courtesy of Cheshire Figment, Co-Moderator disABILTIES board on the closing stages for the parks.
Stage 1 - The parking lot entrance is closed. You can only access the park if you are using Disney Transportation.
Stage 2 - The ticket windows are all closed (and the automated Ticket Vending Machines are turned off). Unless you already have a ticket you cannot get in.
Stage 3 - Only people with Annual Passes or current Resort IDs will be allowed in.
Stage 4 - Nobody is allowed in.
Note - having restaurant reservations in a park, even with written proof, will not override a stage closing for you.
and I was wondering, what resorts or areas can you see the fireworks 
from with out attempting to get into the park? We are staying at CSR and probably wont be checking in until 9:30 pm (hopefully no later)
