Hi we have hired a mid size SUV from Dollar via US care hire although not in Florida in California, There are 4 adults travelling and although I know the car is well big enough for us all I am not sure if the boot will big enough for all the lugage we will have 4 suitcases and some hand luggage. I am wondering if it would be best to upgrade to a larger size SUV. Has anyone any experience of how much luggage will fit into a mid size, any advice welcome thanks.
