Yep. We got there just before the crush but soon noticed the incoming swarm as we were struggling with the fingerprint issue. Longest wait was for luggage, we were curb side in approx. 20mins.
Cant be any worse than Guam about 10yr ago - people were fainting in the queues while waiting.
I've been through Customs in Guam twice which would have to be the quickest US Customs anywhere. There is an ESTA queue which hardly anyone uses as the majority of tourists from Japan, Korea & Taiwan use the non-ESTA lanes.
Used the APC system at Oranjestad Airport as you pre-clear US Customs in Aruba (like you do when flying Canada to the US).
