Before Guanacaste (LIR area) became what it is today luxury resorts, there was Tabacon up by Arvenal Volcano or Los Suenus Marriott Resort and Golf, which is apx 40+ miles from SJO. And is on the way to Manual Antoino Park in Queppos and a few mins drive from Jaco Beach (surf city) although LS isnt on the beach itself its not far from one which is down a side road from the hotel we walked it
I wasnt there in a number of years when I was there I wouldnt have said its luxury in any sense of the word , but it was a very nice maintained place, very large twisting pools
