Not a good candidate for conversion to Club Sunterra. Can't tell you exactly how many SunOptions it would convert to since it's a Float and not a fixed week, but I would guess 4000 -5000 every other year since it's a biennial. That's not a lot of points to go with conversion costs and annual Club fee of $149. If you do a search on Sunterra on this BBS you'll see lots of examples of GREAT conversion candidates found on eBay many of which haven't been moderated out.
