Thanks guys I appreciate the info - for those that don't know its basically just a high alcohol content liquor (144-160 proof) thats been banned in the US since 1912 because supposedly one of the ingredients its distilled with, called wormwood, makes you hallucinate. Science has proven that this is not true though, and the stuff you can buy in the US is not authentic high quality Absinthe - its wormwood free. Most of the time Americans drink it across borders because it does give you a very strange drunk, and like I said, the good stuff is still banned here.
A few more things - where are the liquor stores in Aruba? Are they close to the resort areas or do you have to go more inland? And also can you buy the stuff in any liquor store or is it just a select few?
