Westin Pasadena is nicer hotel, but the hotel is not platinum-friendly. They don't upgrade platinum that often. I had 5 stays in this year and I didn't receive any upgrade on my stays. It is always like what you would get is what you paid for. They didn't even honor 4pm late check-out sometimes. I was turned down 3 of 5. The hotel doesn't have club lounge. So I felt like there was no benefit for a platinum with this hotel except for amenity points. On the other hand, Sheraton Pasadena has club lounge and they tried to give upgrade all the time and I didn't have trouble with late check-out even once, which is very nice.
