I purchased these previously from the Westin Store last year and they definitely smelled like going to the Westin. I'd walk by the diffuser and then smile since it brings me back to the Westin in Maui. I just opened a new diffuser and I am not sure if I received a bad item or perhaps they changed the scent. The scent is no longer the same. Comparing the Diffusers side by side, the new Diffuser smells muskier and not quite as refreshing. If you truly miss the Westin, don't mind spending the money, and crave the scent, then purchase the product. It's still fairly close to the Westin Villas scent.
We stayed at a Westin Hotel a few years ago and the whole hotel had this scent. I loved it and had to bring some home. They say it lasts around 3-4 months but I enjoyed mine for almost 2 years. I would give this product more stars but it is so expensive . I bought mine on sale.
