Transportation will be via car or shuttle mostly as most off-property hotels offer these services for free. Rental costs range from $20-$30 per day, and Uber/Lyft from around $35-$50, depending on the distance.
Arrive early when park capacity is at its lowest, and make sure to reserve any rides, restaurants or shows in advance. If you have limited days, prioritize which parks or attractions are a must-see, and adjust accordingly. It can save time and reduce stress.
