DEG, that is a moot point since the programs are being merged into one (for answers to your question read the older postings by changing the settings to see postings older than the default 20 days).
I spoke to Westin Premier on Nov 30 and they still did not have any more information on the changes to the program. This does not leave me with a lot of time to decide whether or not I want to transfer my Westin points to Sheraton.
