Is there any charge for parking for Disneyland?

Yes regular parking for a standard size car is 20. Preferred parking is 35. Not sure what the fee is for SUV, oversized truck, or bus/limo type vehicles

Of course there is!!!

Yes $20

yes parking is pretty expensive, some nearby hotels will allow Disneyland guests to park in their lot if the hotel is not booked to capacity for a fee but it is usually less expensive (I believe the Anaheim Hotel across the street from Disneyland allows this). It is definitely worth it to find a hotel within walking distance or to find a hotel that offers a shuttle to Disney.

Yes, but you could use uber

Yes currently it's $20.00

Uber drops you off and picks you up at the entrance.

No. It's free.
