I flew in on a Saturday morning. My husband and I walked to ARC (.... bad idea! don't do it! It was less than a mile so we "thought" it'd be easy.. except when you end up getting to the end of the path .. there's no way to cross the road! Running across with five suitcases is NOT fun) and sat down, my cat was ready within an hour. So, it was probably 2 hours total? However, I saw people leave quicker. Like having only sat down for 10/20 minutes and their animal was ready. I stayed in ARC for a while, speaking to an American whose cats were Quarantined, and most people were out within an hour.
