While there is probably not accurate data available, I am curious as to the extent of the program merger problems. Do the problems appear to be greater than reality in that we FTers generally post the negatives on this forum; not so much the positives? In my case, I have been a loyal MR member for many years with no problems prior to the merger. After the merger, I took the opportunity to try several SPG properties. In many stays since the merger, the worst problem that I had was a reservation that was not e-mailed to me. Upon arrival, my reservation was on file, I received the designated benefits, and my stays/points posted accurately. And my SPG stays/points merged into my MR account without issue. That is what counts for me.
If nothing else, the merger, with all of the FT posts, I received a good refresher of the benefits that are designated for my status.
