+100000 to the OP.

And Marriott is an absolute joke on this front. I had a similar thread about a year ago because at one point late last year I stayed at 7 straight different Marriott properties in multiple states/countries and none of them gave me feather free despite the fact that it was (a) in my profile and (b) i always submit a request for additional foam pillows when i check-in and put a request for a feather free room in the additional comments bar when I do it (and they always acknowledge both the pillow request and feather-free request).

It's 100% ridiculous -- actually when I wrote them about those 2 things they claimed it wasn't in my profile, except I added it to my profile in 2012 when I started staying at Marriott's -- I'm not stupid I didn't just suddenly develop this allergy and spend the previous 400 nights just accepting feather

This is one place where Hilton has always been pretty on-point for me -- they always seem to at least have foam pillows in the room even if they don't de-feather and 9/10 times they have it feather free for me when I check-in.

I've always assumed it's because feather pillows are cheaper and most of these hotels are cheap but there is no reason not to guarantee these requests, especially when booking far enough in advance that housekeeping can make the changes as part of their normal process in turning the room over (I understand the scenario where you book last minute and they simply don't have time).

I've also had a few experiences where I actually got an upgrade (yay) but then of course they didn't carry over my request so it became a big thing to get them to change the pillows and bed (happened to me at one of the Ren Paris hotels a couple years ago, arrived late night, the upgraded me, I just wanted to sleep and it took over 60 minutes just to get a foam pillow -- so I went from 5 potential hours of sleep to 4).
