We did WDW before our 4 day cruise, and originally didn't plan to do anything but sightsee after our cruise returned before our plane left Sunday evening. However, I changed our minds and we went to MGM and had a blast. There's not as much to do, so not so much pressure to DO everything. (We rode Tower of Terror six times!) I agree with Jwann- there was a bit of a let down feeling that was helped tremendously by going.
