I am looking at booking flights on points in Business/First from CUR-MIA-BOS, if relevant I am EP, as this is an international itinerary in business/first would it be reasonable to expect to get lounge access included in MIA? The main reason is we're looking at an (intentional) six hour layover as one member of our party will be heading off elsewhere as a UM from Miami so we need to allow enough time to facilitate that.

From what I've experienced flying international/business gets you in the lounge, just not sure of that holds true for shorter business trips on points.
