If I am not at the Alchemy bar, I love an Ultimate XO.
At Alchemy, I usually start out with the lavender thing they make. Later, I'll ask the bartender, "do you have time to create a new drink for me?" I will answer a few questions from them (what alcohol? bourbon or vodka or rum, based on my mood. Sweet? No. Spicy? Yes, but not over the top) and then I sit back and see what they come up with. I am rarely disappointed.
The Alchemy bartenders know me quite well by the second day of the cruise, it's my favorite place to hang out.
