They are tasty, but we thought "lite" on alcohol.
I want to say those slushies in France were like $8 or $9 each...they were probably the most expensive of the "slushy" drinks we had on the World Showcase. I don't have my notes with me right now, but IIRC the Sultan's Colada, the Italian "Margarita" and the rainbow Margarita in Mexico were all in the $7.50 range but the French drinks were more.
