Fodor's "The best vantage point for the Sheraton's dramatic cascading waterfall (the rocks are fiberglass) is from the Dining Room restaurant or the Lobby Bar, where a pianist plays in the afternoon and a live band performs in the evening"
Star Service "Club-level guests enjoy upgraded amenities plus access to a private lounge for breakfast and evening drinks and snacks"
