I found a really great deal 5 nights, swim up room, non stop flights in September with Expedia & now it's up the past 2 days. About $200. I've been looking for over a month now & it went down about $100 but now up $200. Is this how it normally is? Which sites have you found the best deals, any promo codes, best day or time? Once I have the best price my TA will match it. Looking to book in about 3 weeks or so.
