My wife and I had high expectations of W South Beach having had an awesome stay at W Hong Kong. Despite arriving at around 12.10, and despite staying in one of the entry level rooms we weren't given access to our room until after 4pm. Checkout was 11am - a full five hour gap, which I think is the longest I've ever experienced. The room felt like it had seen more than it's fair share of partying. But... great lobby.
