Richard,
Thanks for asking your question to planDisney!
Yes, Disney accepts credit cards for payment when you park at their Theme Parks! You will find that they are fast with the billing, so you will not be holding up the queue, and they will have you on your way quickly.
BONUS TIP #1
You sound like a Walt Disney World veteran, so it is probably not news to you that if you change parks during the day, your parking pass purchased at your first park can be applied to the other theme parks that same day. So, you don't have to keep paying if you are inclined to Park Hop!
BONUS TIP #2New to some guests is the Preferred Parking option at the theme parks. These spots are closer to the theme park entrances, so if time is of the essence, you may want to pay a bit more for this perk.
BONUS TIP #3The courtesy trams have returned to the parking lots at the Magic Kingdom Park and are reported by Disney to be returning to the other parks throughout 2022! Keep an eye out on the
Disney Parks Blog for announcements of their return to other parks.
Write me back if you have any follow-up questions.
Have a Magical Vacation!Doug
