This is a genuinely simple dessert that works for a Charlotte kitchen: vanilla ice cream and cream soda are stocked year-round at every major chain, and spiced rum is readily available at any ABC store. It costs roughly $2 to $3 per float depending on ice cream brand and rum choice, making it affordable for an occasional treat. The stated five minutes is honest and accurate, requiring no prep beyond scooping and pouring. The main limitation is that it's a same-night indulgence with no leftovers and requires constant attention to prevent melting, so it's best for a single person or immediate consumption rather than a family meal.
