Ya I have no clue about your resort or instructors many members are just giving general advice on how to advance.
If you are struggling that bad or the resort isn't to your comfort level, you may want to take that trip to the other resort you mentioned.
Do you have a large sledding hill in your city. Not just that golf course, one where you can get some momentum. We have a great sled hill, never used it to learn snowboarding other then when the kids had the cheapy boards that aren't real snowboards. I have seen many kids riding it. Good riders and begineers, this might be a good free option.
