I have had to fax in 5 missing stay requests in the last two years and have always had a quick response--about 48-72 hours for the stays to post.

I usually have no problem with the credits posting, but it seems there is a problem with some of the resorts in getting credit. I just save my receipts and watch for them to post, and if not, the fax works great for me. The other time I see a problem is when there is a promotion going on, such as the latest 30,000 mile promo. I had 2 stays not post which I had to follow up on.

If it goes over 72 hours, I would make a call.
