Which broken Marriott website? There are at least two different Marriott websites!

Some pages are on the new website, but some pages are on the old website. The Marriott logo my browser displays for each open tab is slightly different for tabs that have a page from the new website vs tabs that have a page from the old website.

If you want a simple way to get to the old website, log into the new website, then select Overview, then click Nights (which probably only shows lifetime nights, not lifetime points any more), then click "learn more", and you're immediately thrown to the old website where you have to log in again! There are other links on the new Marriott website which take you to the older Marriott website, but the above is the one I use most often and thus remember by heart.
