3.5 hr flight from San Juan to JFK (4 hr layover)
6 hr overnight flight from JFK to London (7 hr layover at Heathrow)
11 hr overnight flight from London to Cape Town, arriving in Cape Town first thing in the morning
Since we would be traveling for 2 days straight we needed a shower and a nap in London. Unfortunately, 7 hours is a bit too short to make heading into town worthwhile, so we booked a Yotel Pod at Heathrow. Essentially, for about $40, we got a room the equivalent of a ship cabin for 4 hours. You get a bed, tiny shower & bathroom. It was perfect because it was close by (in the airport terminal), pitch black and quiet. We slept for about 3 hrs (much needed since we didn't sleep on the plane), and then used the last hour to shower and change. Afterwards we had enough time for dinner before we boarded our long flight to Africa.
