No, the 4 day ticket is for the Disney parks only. Can only be used by one person per day. Is there a ticket that allows me to go to Disney and Universal. Disney, Universal and Sea World are strong competitors.
Disney tickets are good for the number of days listed on the ticket and never expire.
1 day tickets to Universal, Islands of Adventure, Seaworld, Busch Gardens, Etc, may be used any day. Does not apply to the Flex ticket . Some Dinner Show tickets may have an expiration date on them. Kennedy Space Center will Expire on the 30th of December each year and are not good for New Years Eve events. Other restrictions may apply to special events.
