2014 Points
As of now, if you talk with DRI, depending on with whom you talk, you may get a different answer. However, as of now I have consistently been given the information that resale points do NOT have access to Interval International if you are in the US Collection. We have had a great debate on this on the DRI Members Forum on Facebook.
Apparently in the European Collection, they have access to Interval International. That may be part of the problem being communicated. There are some subtle differences from collection to collection.
The points from 2014 may not carry over to the new owner in the transition. The 2014 points will still belong to the original owner. What the new buyer will need to do is have the original owner make reservations for him/her so that they can access those points. Owner services explained this to me last year.
Remember, if you buy resale all you are buying is access to resorts in the collection from which those points belong. Know also you will need to pay to belong to the Club in order to have any other benefits. I would also inquire as to which resorts you will have access to within the collection. Because there are some resorts within a collection that are affiliates that you will have access to and others that are affiliates that you may not have access to within the collection. Get everything in writing prior to signing so you know with what you're dealing.
I would also get in writing if you have the 13 month home collection advantage to make your reservations and if you are able to save your points from one year to the next. There have been conflicting messages on that as well.
