In your quest for knowledge keep in mind that RCI and II are not your only trading options. There are some smaller trading companies out there like DAE, TPI, and VRI*TY to name a few.
Some don't use trading power and some do. I use DAE almost exclusively. The exchange costs are lower than the big two but the availability is nowhere near what the big two offer.
Despite what Denise said about Orlando being overbuilt, DAE lists it as one of their Prime Time areas and often gives extras when depositing one. The last couple of years I got 2 exchanges for each deposit. When I locked off my unit I got 4 exchanges for my week.
Keep asking questions and studying, it takes a lot o
f time.
