Arenas Del Mar was a stop on our honeymoon and we absolutely loved it. Of course, it's a beautiful resort, but that isn't why you should stay there - you can get a nice hotel room in a lot of places - You should stay there because it is a haven of nature that really felt unique and special. We saw more wildlife on the grounds of Arenas Del Mar than we did in Manuel Antonio Park. Macaws, anteaters, monkeys, sloths, you name it! You can walk to the beach (both a private one and a public one) and the staff are incredibly friendly.
