A fresh Ultimate owner myself, I would plan on starting out at 100% and then taking on some juice in Merrit. Not a full charge, just an hours worth or so, maybe to 60%. I would go PetroCan. Probably not free anymore but that's the way it goes

Too many stops defeat the capability of the Kona and I would think charging a near full battery takes extra time and is unnecessary. Just my own opinion and how I plan to drive. Went to Hope for brunch the other day, just for the h... of it. had 100kms+ left after 275km.
Now, if you have range anxiety, disregard what I said and pack for a long trip
After some extra thinking... Since this is your maiden drive I suggest you grab a cup of coffee at Hope while making sure DCFC actually works. You'll be at about 70% so taking it up to 80% shouldn't take too long and will confirm all ok and if not you'll have enough juice to divert back to dealership. Just a thought
