hi claire I can answer a couple questions My husband snorkled at los arcos and I cant remember the other (sorry)it was when we wwent to piedra blanca he much preffered los arcos for seeing different types of fish.
As for cheaper booking here or when you get down there IMO there is no prce difference so for the convenience I would book here and then everything is in place and set up for you. Hope this helps a bit.
