We were in the Galapagos earlier this year. For insurance, we booked just the evacuation insurance through Travelsafe. The cost was $108 for us both. We have a premium credit card that provides travel insurance, so we didn't need the whole package. If you have a premium credit card, check your benefits.
Also, we traveled Delta through Atlanta and it was surprisingly easy and efficient. Our connection was 5 terminals away and we had 1 hr to get there. I was a bit stressed, but the monorails were great and we had plenty of time.
