The Galapagos tour is one of the easiest to pack for. We have taken it twice. You need no dress up clothes. It’s easy to stay under 44 pounds. On this tour just about two years ago, one of our checked bags was ruined on our return flight, it was very wet, but we soon discovered it stunk of fish when we collected it and rechecked our bags at Miami. It must have been stored near a fish shipment. We had to throw taht almost new bag away and could not claim on insurance since it’s not possible to send a photo of the damage, you can’t photograph a terrible smell.
