With my 90D when off the beaten track I have used 120v with success. In summer you get 1.5%/hr at 12a. So figure out how much time you have when you arrive before you need the car again. Maybe plan a 1 hour stop at the winery destination charger for an hour if needed.
Below freezing may not be a problem. If it just below freezing, above -5o (all temps are Celcius), and you hook up you car to charge as soon as you arrive witt your warm battery (ie 1hr+ of highway driving) the battery will not get cold enough to not charge. If is is a bit colder but still above -15o and you hook up to 12a 120v as soon as you arrive you will be able to charge for 36+hrs before you battery gets too cold. An acquaintance reports that -8o is good for >48hrs of slow charging. I do not have experience with 120 v charging below -20o.
Definitely look into 120v 20a (one third more power) or any 240v (especially stove & dryer plugs) plugs as the latter can make winter charging effortless with the right adapters.
If you know that your 120v12a (NEMA 5-15) is not GFI and you can get access to 2 opposite phase 120v plugs then buy a Quick 220 and a NEMA 6-15 adapter for you UMC. That gets you double the rate of your standard NEMA 5-15 and as long as you plug in as soon as you arrive then anything above -10o will charge like summer.
After you car has sat for >12hrs the battery will cool enough to put some limits on regen but not on charging.
Before "starting" your car to leave, turn on Range Mode to stop the battery heater from running.
It is a bit of a nuisance checking out the electrical supply at where you stay but you can usually find something that works.
Try and talk the owner into putting a outdoor (in enclosure) NEMA 14-30 or 15-50 plug. With the right adapter you will get a full charge overnight even in the winter.
