airline/hotel price drops?

[pdxJolene]

I'm going to be going to DL with a girlfriend April 15-18th. I've been watching hotel/airline package prices on expedia, priceline, lastminutetravel, etc.. And prices have been dropping pretty significantly over the past week and a half or so. We started out at $680 (2 tickets PDX to LAX and 3 nights @ hotel menage) and have now managed to get it down to $550ish. I really can't imagine prices dropping any more, thats SO cheap already! But, thats also what I said once it was at $600. Any advice? I don't want to wait too long to book and have prices skyrocket.
