Booked a pre-cruise hotel for my parents - they're thrilled to be staying at the Westin! In: 4/30 Out: 5/1 Started with $70 and kept adding free re-bids, and increased by $5 each time. Took 4 tries ~ finally accepted at $85, plus $17.46 for a total of $101.46. The hotel website direct, pre-paid internet rate is $209, plus 10.5% tax for a total of 230.95. Thanks to priceline, they saved over $129 or 55%
