Yes, Florida Resident grandparents can purchase Disney World tickets for their family members, but there is a major 2026 catch: every adult (18+) using a Florida Resident ticket must provide their own proof of residency. While a grandparent can pay for the tickets for their out-of-state adult children, those children will not be able to activate or use the tickets at the park unless they also have a Florida ID or qualifying utility bill in their name. However, grandparents CAN buy and activate Florida Resident tickets for their minor grandchildren (under 18) without the children needing their own ID, as long as the grandparent provides their own valid Florida proof of residency. In 2026, Disney is very strict about this to prevent "residency fraud." If you are planning a multi-generational trip where the adults live out of state, it is usually better to buy standard "Guest" tickets for the adults and only use the Florida Resident discount for the Florida-based residents and any accompanying minor children.
