We highly recommend enjoying the Tambu Lounge and experiencing Trader Sam's lounge at the Polynesian. Both were very crowded (we visited Tambu during a torrential rain so our visit might not have been typical). The drinks were excellent (also light food at Tambu) but most amazing to us was that even with the shoulder-to-shoulder patrons, the waitstaff were always pleasant and even calming. I don't know how they do it but you won't regret giving these lounges a try. And take your time at Trader Sam's ... little surprises pop up all the time.
