I have stayed at one particular Marriott -both using points and paying for nights- and every time I use the points they enter the arrival upon check in - and when I check the site a few days later they are not posted. This is not the first time this has happened - they updated visits in the past. However, reference to the current missing dates- I have brought this up to the hotel many times. I have written and submitted to the hotel the dates and info of the missing the arrival points - and still nothing. I have three different dates STILL without the arrival points applied. I am a platinum member and have achieved my nights needed this year to remain as such. Advice???
