It sounds like our travel plans are simular, I am arriving for a short visit on a Tuesday and will be in the World thru Sat. I have found that visiting MK during the week to be much better than the weekends even during peak times. To help you decide double check the calendar of events and find out the park hours, and number of times Spectro and Wishes will be presented. Spectromagic has always been our favorite parade, maybe because we got a sneak preview of it on our first visit in 1996. I love it so much I have a CD with all the music. I can't give you an opinion on Wishes yet, but the video on this board is fantastic, I can't wait to see it in person.
Here is my plan for Tuesday (commando style), check in to POR or leave luggage (arrival time Noon) and go to MK, get FP for Philharmagic (top of my must do list), check out park till ride time or if long. . . catch the monorail to the Poly for lunch at the Kona Cafe. After PH and lunch enjoy shops, rides, etc what ever I can get into till dinner PS at Cape May Cafe, return to MK for Wishes, head back to POR, unpack and bed.
