Basically, when you add on it IS to your current contract. The difference is that it will have a seperate additional number. We have 3 contracts. They all have the same contract number, but each additional add on is noted with a -# after it like 12345-1 12345-2 12345-3 etc. You can't actually add points to the 100 to make them 200, but your additional 100 points will be tracked the same way. Now if you by KTV once it comes out, your contract will be the same number with one of those -#s behind it, but it will be a seperate home resort. If you want a totally different use year for your new points, you would have to buy 160 points.
