For anyone who wanted this recipe, I heard back from Disney today and got it from the bartender at the Dawa Bar:
1/2 oz. Myers Dark rum
1/2 oz. any type of brandy
1/2 oz. creme de banana
1/2 oz. blackberry brandy
2 oz. orange juice
2 oz. pineapple juice
1/4 oz. grenadine
2 oz. sour mix
Combine above ingredients and shake. Place 1 oz. Bacardi 151 rum as a floater. Garnish with an orange slice or cherry.
