Really you should not worry about bringing your Tesla. There are Superchargers open in Florida City and Plantation. Numerous supermarkets, shops, hotels and public garages have L2 charging available. The Brickell Superchargers are nearly complete and may open still in December, although realistically it's probably going to be January.
There are a quite a few destination chargers too, and a number of CHAdeMO if you have an adapter.
If you plan to be around Brickell, the Hampton Inn had both destination charger and J1772, they work perfectly and are free except for the parking fee, which in about the cheapest in the area, FWIW, I use that one myself quite frequently.
Should you shop, Sawgrass Mills has a string of four J1772 that work perfectly. Almost everyone who goes there spends hours so if you're in a hurry. Plantation is close by.
Bal Harbour Shops and the ST regis both have Tesla Destination Chargers.
I'm only mentioning ones that are free. Aventura Mall has paid ones at Nordstrom and Bloomingdale's. All over South Florida there are lots of options, and more arrive almost every week. Superchargers are doing so too, just not quite soon enough for you.
I spent several months with no charger in my condo in Coral Gables. It ended out being quite easy. Much more so now, three years later.
BTW, driving from Miami to Quebec City and back when I did that last year ended out being quite easy. Now it's even easier.
