Are you renting a car or doing transfers. If you rent a car once you are in the car 1/2 hr max. If you are doing transfers it can be longer because they may make multi stops at other resorts.
If you're doing the Mears shuttle, allow at least 90 minutes. The shuttle will stand at the airport until it is full. Then it will stop at a series of hotels and there's no predicting where SSR will be on that list.
