Thanks for all the ideas.
But, DL flights arrives about 8:30 PM and departs 8:00AM.
That is not the best time of day to go sightseeing sadly.
I would love to go see the area but not very practical to do at night, is it?
As far as lounge access, I have Skyclub card. I dont think that gets me into the Copa Club does it?
What does a day pass cost?
