Hoping to rent a minivan at SAN for a one-way in California rental thanks to the advice from this forum. My goal is to reserve a car and select a minivan in the row.

Would it be better to reserve a midsize and hope there's a minivan in Emerald Aisle, or reserve a fullsize and hope for a minivan in Emerald Reserve? Or is there a better approach, short of outright reserving a minivan (which has much higher fees or no included miles)?

Thanks!
