Just returned tonight. There was a strike going on in which downtown was blocked off from about 1:30pm until ? Our cab driver had to turn around and go a different route. I was happy that we left enough time to allow for the longer cab ride(took an extra 15 or so minutes). Everything worked out fine, but leave yourself about 3 hours from the time you leave your hotel to get to airport just in case.
Our trip was great and I hope you enjoy if you are going soon
