Yes there is a drop off and pick up for families and taxis and lyft / uber
From the Disneyland website, "Please use either of the following locations to pick up or drop off Guests visiting Disneyland Resort theme parks or the Downtown Disney District: Downtown Disney District – Take Magic Way from Disneyland Drive, then turn south toward the Downtown Disney District parking lot and follow signs to the drop-off area."
Yes. It's off of Harbor Blvd
No only for authorized transportation such as hotel drop or buses from the Disneyland parking
Not officially, no. However, you can have an uber or someone drop and pick you up at the entrance at Harbor Blvd. This is actually faater than taking the tram. With the tram, you go to downtown disney, get in the line for the tram, take the tram to the parking structure, walk to your car and then leave. It's actually faster to just walk to what used to be the 15 minute parking area at Hrabor Blvd. and have your ride pick you up or drop you off.
No unless going to Downtown Disney
