We just got off of a cruise a couple weeks ago and purchased our first placeholder. I'm currently looking at a four day voyage in October - but cabins are filling up. Is there any downside to just using the placeholder on this voyage now to hold our spot? if we decide to change our plans later is there a downside? As a novice, I can't see why I wouldn't just lock it in now and then make any needed adjustments over the summer
