Another 'cooler weather' suggestion. There are several brands that make 'spiced' dark rum. I have enjoyed all of them I've tried. Your Rum and Coke will have a nice punch, and I drink mine in a 'snifter' and sip it like high dollar whiskey. Not real spendy, a decent mixer for not much money - and I'm not really tempted to overdo it. These are all good things.
