Hi Hai-Au!
I am sure you are getting excited about your future Walt Disney World vacation. The dream will be a reality soon.
Your Hilton resort is located close to the theme parks so it won't be much of a drive to get to both, Magic Kingdom and Hollywood Studios.
Parking for non resort guests is available but it will be $20 a day. If you wish to choose the preferred parking the cost for that is $40 daily. This gets you a space close to the entrance. You can decide about that at each of the park's entrances.
You can also check with your resort to see if they have a complimentary shuttle to the parks. And if they do not I am sure the concierge can help you with directions.
All of the parks will have
Lockers available for guests to rent each day. They are on a first come basis and come in two sizes. They rent from $7-$9 for day use key lockers and some of the parks also have coin operated single use lockers that will use quarters only. Check out the sizes and know that if you have perishable foods these lockers will not safely keep food safe.
So you can plan ahead please check out the list of items
Not permitted in the parks. It pays to know in advance so you are not turned away at the entrance and security lines and have to head back to the car.
Enjoy your wonderful park days!
