I emailed 2 GM at different properties from the link on the hotel website asking about platinum amenities. One responded quickly having forwarded to correct dept. and said should br followed up in a few days never got a resonse so after a week emailed back saying that I had not been contacted and was a bit disappointed. Return email said there was an error because person who should have responded initially was on vacation. Got the answer the next day. Second property never bothered to respond at all. Guess which one has better reviews for their hotel (spg and tripadvisor)?
