my family is originally from ecuador, but i was born here in the USA. my last trip to ecuador was about 10 years ago, and i was lucky enough to visit the galapagos. it's really a great place to visit - it's like your very own zoo / museum except without all the barriers. even back then, knowing spanish in the galapagos was great, but there are so many tourists that knowing spanish isn't 100% essential. now, 10 years later, i'd say that this is probably still the case.
what kind of schools are you looking to study spanish in? colleges? secondary schools? also, are you going to be based in the galapagos during this trip? or one of the major cities (quito, guayaquil)? finally, how long do you intend to be there? i can reach out to some of my family members there to see what recommendations they would give regarding schools.
