Destin's city center is on the westernmost tip of the peninsula. A number of golf courses, such as the Kelly Plantation Golf Club, dot the peninsula. One of the most popular clubs is the Sandestin Golf and Beach Resort, which also has lodging and attractions along the gulf and bay sides.
Walt Disney World Resort continues to honor all unexpired theme park tickets with remaining admission days. However, be aware that unless you purchased the No Expiration Option, theme park tickets purchased after 2004 expire 14 days after their first use. While the No Expiration Option is no longer available, if you have previously purchased theme park tickets with the No Expiration Option, your tickets will still be honored.
I'm so sorry to hear about your situation, but I do have some good news for you. The Disney Gift Card you purchased does not expire. It is valid for purchases until all funds have been depleted from the card. It is also good to know that there is no service fee for unused balances on the Disney Gift Card.
