Breakfast at W is nothing special, but the property itself is fantastic and if you have Marriott elite status you will possibly receive a generous upgrade depending what month you visit. If you don't mind taking the taxi then W only adds a few minutes of travel time but obviously regarding location travel into the city is not the hotel's strong point. That said, if you plan on spending time at the hotel it's one of those places that give you have worldwide unique unforgettable experience.
