Start organizing what you’d like to do in each park to streamline your process. You’ll need to prioritize what you can, and cannot do. Don’t worry about what you cannot do at ALL. You’ll still have a whole lot of fun. Once you have your list of what you’d like to do, eliminate even more if you need to because of time restraints. Don’t overdo it, because you’ll be miserable - ON AN EXPENSIVE VACATION. Well, sometimes the parents just have to endure it for the sake of the kids. Don’t make your kids miserable, though. You’ll see the miserable kids of others. Don’t pay a boatload for this vacation, and wind up hating it. Relax where you can, and need, and enjoy what you can of it. If you get a plan of attack together of exactly what you’d like to do, that will help avoiding the "where do we go next?’ conundrum, and add to the ease of knowing what you are doing at all times. You’ll already know what is important for you to do. WDW is HUGE, and it has tons of sidetracking diversions.
If you are locked into two days at Universal, and this is your first trip, I’d only do half of a day at Epcot. Kids generally LOVE TT and Soarin, and Mission Space. I’d also do Spaceship Earth, and be done with Epcot for this trip. On the next trip, do more at Epcot.
Hollywood has the best thrill rides, and the Indy show, and the Star Wars stuff, and Fantasmic. A lot of ppl say it’s a half day park. That may be, but I like Hollywood, and 3/4 of a day is no issue for me.
I’d essentially make sure to be at AK/EP/HS for rope drop to maximize what you can do and get out to relax. Early am is precious time for getting things done instead of standing in lines while the line for what you want to do next gets even longer. Your feet are going to take a pounding.
-Don’t overdo it.
-Have a plan to eliminate wasted time on things that are not important to you (this time.) it sounds harsh, but the reality is that whatever catches the kids’ eyes might be insignificant compared to what you want them to see next. They are kids, they don’t know. Let them know beforehand.
-Remember to relax and enjoy this time with your family.
