I did this one on the Fantasy a couple years ago and wrote down everything we had. It was three (nonalcoholic) smoothies from the Senses juice bar, a basic mimosa, and a bloody mary.
The three smoothies were:
"Get Up": Strawberry, banana, sunflower seeds, almond milk, blueberries, turmeric
"Juice Tonic": Bananas, chia seed, apples, kale, spinach, spirulina, water
"X-Press": Strawberry, goji berry, avocado, mint, beets
At the bottom of my notes I wrote "Not a winner."

Part of it is I don't like almond milk but honestly I remember all the smoothies being hard to drink. Looking around the room, there were a lot of mostly full glasses by the end so I don't think it was just me. By all means go for it if you're into those kinds of smoothies, but don't go in expecting a bunch of interesting brunch-y cocktails. Go in expecting spirulina and goji berries.
