How hard is snowboarding?

I have been skiing since I was 3 years old, and I am now 16 years old. I really want to try snowboarding because it looks like a lot of fun! I usually pick things up easily, so how hard would it be for me? I am going to Utah in two weeks and thats when i want to try. I also just got back from Colorado about 3 weeks ago. Can you tell me any tips about learning to snowboard? Also which foot goes in the front? Just write anything that you think is helpful for me to know. Thank you so much!
