I am also into sweet/fruity alcohol! My go-to stuff is things like magaritas, mai tais, champagne, mojitos, and spiked milkshakes/coffee (Baileys Irish Cream, yummm). My overall favorite cocktail would be a Bahama Mama! I sometimes like sangrias but it depends on what's in it.
With the bottled stuff, I like Cayman Jack and hard ciders/lemonades.
