As you all know by now (I am assuming!), the Marriott and Starwood loyalty programs are combining in just a few days on August 18th. We’ve been told that the website will go down at midnight (eastern standard time) and the system will be offline for several hours. While they hope that the system will be back up and running at some point during the day, there is definitely no guarantee. I’ve been part of many system integration “go-lives” and what you hope to happen doesn’t always work out as planned. In your mind, assume that the system will be done all weekend as a worst case scenario.
This means if you know of any reservations you need to make for next week, book them now! Do not procrastinate and wait for this weekend to come as you never know what will and will not work. Of course my fingers are crossed for a smooth transition though!
