I found the selection at Sosa in Downtown Disney to be quite nice...
As I remember it, they had LOTS of hard-to-get Fuente products. As my memory recalls from over a year ago, they had Opus A (complete with coffin), God of Fire, Anejo, and some others (I think Between the Lines and Work of Art stuff).
My guess is that you'll be able to find Don Carlos Anniversario stuff, as well.
Even though I'm well past 35, I felt that the management was all over me while going through the walk-in... May have been the twenty-somethings mentioned earlier in the thread, but it wasn't the warmest environment, either.
Oh, and the price tags will make you go
, but that's surely a function of rarity and Downtown Disney rent!
