How quickly can you learn the basics of snowboarding?

I’m a complete beginner and have never done skiing, XC skiing, or snowboarding before. I will be going to a ski resort for 6 days in December and I want to try it all, is it worth doing a mixture or should I stick to one discipline only? Is it any use trying snowboarding if I’m only going to do it for 1 or 2 days? Will I spend most of my time on the floor? I used to do downhill skateboarding and slalom so I think I would enjoy snowboarding more than skiing, but will I just spend most of those 6 days struggling to learn snowboarding when I can pick up skiing in 1-2 days? TIA!
