I spent two nights at Anaheim Marriott (as part of a group) as we wanted accommodation close to Disneyland.
The hotel is well located; walking distance to both Disneyland and The Outlets at Orange (it's a lengthy but worthwhile walk to The Outlets). You also have the option of a $5 return bus fare to Disneyland.
Hotel staff were friendly and we were checked in several hours early. Rooms and the hotel as a whole is quite dated - it certainly did not feel four star.
Room was an average size, bathroom likewise. Terrible water pressure and temperature. Some of our linens had faded stains - nothing terrible i.e. they had been cleaned, but housekeeping staff lacked attention to detail. No mini bar. Wi fi cost just less than $13 per day; hotel had free wi fi in some common areas. Bed was very comfortable.
By no means a terrible stay but make sure you get a good rate and don't go there expecting luxury.
