Tried making a reservation at an AC in Barcelona earlier this evening; saw availability on the app, so went off to finish some errands and a half hour later, no results for all of Spain on the app. Tried doing the same reservation on my computer, got to the 'confirm reservation' page and after clicking confirm, I got an error page about the site experiencing technical issues. Tried again, same thing, so I called the Ambassador line who tried to work it through but got no availability for the same duration. I checked my e-mail and then saw two confirmation e-mails for the hotel in my inbox, so the reservations apparently went through... twice! Another call to the Ambassador service and one got cancelled.
Yeesh. Shame on Marriott and their total lack of having any semblance of IT sh_t together.
