Deciding on my next big race

Will I be an IRONMAN at Cambridge, Maryland (Oct 7, 2018) or an IRONMAN Louisville (Oct 15, 2018)? I've narrowed my next big race down to those two. The Maryland course would be easier but it is flood-prone and could get cancelled. It takes place within a wildlife reserve, so it would be a beautiful ride. I'd be able to visit my aunt and uncle, and it's an hour less each way in terms of getting there by car. I'd have to take two days off from work. There are no hotels near the race site, so getting there on race morning would mean an even earlier wake-up time. The Louisville race would be a little more physically challenging, it would not involve visiting family, the route is more urban (not so pretty, but maybe less boring), take a little more time in the car to get there, but only require one day off from work instead of two.
