Will be at Disney Oct 21-Oct 29, and planning to go to Universal for 1 day that week. Thinking about a 2 park/1 day ticket. mainly going to IOA for Harry Potter, Spiderman, Seuss and Jurassic park. Then would like to head over to Studios. I'm looking for input on crowds for that week in Universal. I keep reading that October is a lower crowd time, but does that include Halloween week? Where can I find last years park hours and dates for their Halloween party? Or does anyone have a good guess as to when they will be announced for Oct 2011? Is it even worth it to try to get to both parks in one day? We have been to both parks before, so just looking to hit some old favorites in both parks. We are staying at Disney, but planning to getting to Universal for rope drop. We definitely will not be going to their Halloween party!! too old to handle that kind of fright!! lol MNSSHP is more our speed!
