I haven't ridden at the resort going on four seasons now.
Here is the thing. The powder days are always better in the bc than at the ski area.
You'll get more fit doing it and avoid the shit show that is the resort.
There are a few days that you may actually want to go to the resort. Because of the retard amount of snow that fell over night or something along those lines. Pay for that day if you must.
Otherwise, I'd just split. Hell, when I plan snowboard trips now, I plan them around going splitting in the backcountry and not riding at a resort. So far I have no regrets.
I do like the freedom of deciding for myself what is safe and what isn't. Being away from the crowds and out in stellar scenery is another perk. Lastly, the runs are generally of much higher quality than inbounds. That seals the deal for me.
