(USAToday) - Starwood's Sheraton chain is rolling out new wine menus and a wine tasting hour in a bid to give guests another reason to socialize in hotel lobbies while boosting wine and food sales. Unlike boutique hotel operator Kimpton, Sheraton hotels won't offer guests a free, full glass of wine each evening. Sheraton is, however, going to give guests two-ounce samples of premium wines that received high ratings from Wine Spectator.
