Wow! We all seem to agree. Can't wait to see if you feel the same way or go differently. Thanks for all the pictures! It's fun to be part of your journey.
I grabbed at Otovalo/Cotacachi for two reasons - I just spent 10 days in Costa Rica swollen from the heat and a place that has relief (as a mountain girl) sounds divine. But truly it was your description - you sounded like it would suit the family better. Go with your heart when you make the decision! But no matter where you choose, it'll be perfect for you.
It seems from reading that there is a connection with Otavalo/Cotacachi.
I like the word Banos, because there is never enough when you need them.
Voting Otavalo/Catacachi. "Reflectively listening," I am not hearing many negatives about the area, and lots of heartfelt positives. But I know you will all know exactly where to go!
You sound the happiest there and it is so much to offer. Go with your gut, not your brain. It knows!
