We loved CBR!!! It was beautiful, tropical feeling, etc. We were in South Trinidad, and we didn't mind the walk to OPR at all, but didn't have kids at that time.
I haven't stayed at POR, but I looked at the pics on allearsnet, and the rooms just didn't appeal to me at all, I didn't like the colors, etc. Just a personal thing, but I don't think I'd want to stay there.
