I still have a couple of certificates from St. John Westin for 50% off of rack rates, max of 5 nights. It's been a while since I've used these, but can anyone give me a pointer on how to combine it w/airfare from muggy Iowa to get the best deal....for 2010? We've been hitting STX for the past 6 years and want to go to STJ next year. Any input would be appreciated. The darn Iowa humidity, and lack of ocean, is a killer!
