Hi Michele! Welcome to planDisney! Thanks so much for stopping by to send us your question!
When Walt Disney created 
Disneyland, he had guests of all ages in mind! I'm happy to hear you're planning a visit to experience the magic of The Happiest Place on Earth! When 
purchasing a Theme Park Ticket for a 74-year-old guest, tickets are the same price for all guests ages 10 and older. The price is determined by the date you choose, as well as the number of days chosen.  
As you're planning your visit, be sure to 
make Theme Park Reservations for each day of your visit and each person in your travel party. Once you arrive, the 
Disneyland Mobile App is a quick and easy way to access your Theme Park Tickets, check attraction wait times, dining options, and much more.
If you have more planning questions, please feel free to send them to us at 
planDisney. We're all ears, and we would love to help!
Wishing you magic,
Lisa
