One of the biggest issues with MarBrisa is the costs. The buy in may be lower, but the maintenance fees are pretty high compared to Vegas or Orlando. I know at one point, the activation fee was much more than most resorts. That may have changed, but when I was looking to buy, it was the case. If you are looking for just points, MarBrisa may not be the way to go. If you are looking to use it as your home resort and actually stay there, it’s a great resort in a great location.
As far as affiliates versus developed, there really is no difference. Some Tuggers, like
@Panina, swear by their affiliate resorts. Others prefer the developed resorts. As someone said above, only 2 affiliates have left HGVC and at least one of them was member driven.
