If you go to the theme parks page on this site and click on park hours, you can type in the dates of your trip and see the projected hours. These hours are based on historical patterns and will most likely be different - especially with all of the recent cutbacks.
What I would like to know is what the spectromagic/fantasy in the sky schedule will be in August. I am going 8/11-8/22 and am wondering if they are in the "Saturday night only" mode at this time of year. This seems to be the case everytime I go (usually May or September) and the crowds are just crazy at MK on Saturday night. Add in the August heat and humidity and I may just skip it if it is only showing on Saturday. Are there any "August Veterans" who can let us know what their experience has been?
