Not sure. Just used priceline.
I had to put a very large authorization on my credit card so make sure you have a big limit card.
Make sure you visit and stay on the volcano lake near Santa Ana.
Stay at an upscale hotel right on the lower lake (on right) Swim, jetski etc. my son loved it there.
We stayed the Cardedue Residence and it was amazing. (food is mediocre)
A nicer room there is recommended for views. ~$200 US when we stayed two summers ago

^Its an hour and half from the airport.
El Zonte is like 45 min from airport $25-$30 cab depending on time of day. Past dark is pricier. Maybe $45
You really don’t “need” a car. Last summer, I took a taxi to El Zonte, then I hired a tour to Santa Anna. Spent 3 nights there and taxi’d back to airport. I don’t think I’ll bother renting a car again.
