Four Nights as Good as Seven?

[BreauCat]

We are in the countdown for our second Disney cruise - sailing on the Dream March 4, 2013. We did our first cruise with DCL in 2011 on the Magic and absolutely loved it - so much so, that I'm not sure why we didn't book another while on board. That is something we will certainly do this time - book our third cruise for 2014 before we disembark. I'm enjoying all the prep for this upcoming cruise -especially the Fish Extender gifts I'm planning and making. I am a bit apprehensive, though - our first cruise was 7 nights and I felt we had the opportunity to do most everything we wanted to do while on board. Because of scheduling, we are doing a 4 night cruise this time and I'm worried we may be disappointed with the duration of this cruise. I guess that will be incentive to book a third cruise Anyone else cruised with a shorter itinerary after doing a longer one?
