We've been to Aruba half a dozen times and clearing US customs there is great. You have to be at the airport hours early so why not take care of customs before leaving? We once had a delay getting into CLT on a flight originating in Europe and US customs was short staffed after midnight. Took well over an hour to clear. We'd rather deal with that on the departing end. We now have Global Entry, so it might not be much of a problem, but you never know. Can't remember who reported the comment from TSA about precheck, but it went something like "if we're really busy we close the precheck line." <img src="http://www.traveltalkonline.com/forums/images/graemlins/duh.gif" alt="" />
