ABRP shows[0] plenty of Superchargers along the route and a suggests only a total of 50 minutes of charging which are nicely spaced for eating and breaks, although I'd probably add a buffer in there as well.
Round trip[1] has more stops, obviously, but easily doable without any more planning than getting in the car and driving.
The i4 is a cool looking car, but maybe you could rent a Tesla from Hertz (the devil) or something like Turo and give it a try?
