It used to be when you made a reservation online there was a section for comments - ie, request upgrade if available, wife arriving before me/let her check in, etc.
At some point in the last few years it got switched from the main part of the ressie to Guest info & you went in & did an edit there to add the comment (thanks to VickiSoCal on FT for finding where they hid it when they moved it).
Now I don't see it there, so are comments no longer part of the online reservation process & we'll now have to contact a Marriott agent to add comments? Or did IT move it once again to somewhere else?
If it's the former, that's not really efficient for either the guest or Marriott.
