I was there last year, and some of the runs were pretty crazy, but that doesn't mean all of them were. My mom tried skiing for the first time out there, and she was going through the whole mountain by the second day, but ski and snowboard progression are a lot different. I went on Miami Beach a few times with her, and it wasn't all that bad, there were things that could challenge a beginner there for sure.
So I guess it comes down to: do you want to spend more money and run the risk of going over your head for the possibility of better riding, or do you want to save money and be safe, but maybe miss out on some progression.
If you waited till later in the year, then they might have more options to get down the whole mountain without any trouble
