I actually never expect any reductions. Almost all of my cruises are booked when the itineraries are released. I almost always book group rates through my TA so I'm already starting at a reduced price. The only time I have gotten a reduction in the last year has been on a cruise in 2025 that I booked a GS on and it dropped a tiny bit.
I used to check religiously now, if I have time, I'll go through them once a month. When you book right you don't really have to worry about price drops.
