Woohoo, Teresa! I can't wait to read and see pics of your adventures. I am sure you know most of these, but here are a few of my favorite WDW tips (and I go peak season every trip)...
1. Shoes...if you are prone to getting blisters or already have one forming use deodorant. Just before you put your shoes on and walk out the door, rub it on the sides of your feet or back of your toes. It will prevent them from forming. I used to have a horrible time with blisters and would always end up in First Aid because they got so bad. Once I heard about this trick on the DIS, I haven't had a blister since...and that was years ago!
2. Fast Passes...Use the FP strategy of always having one while you go on a non-FP or short line attraction. Remember that you do not have to return within that hour window printed on the ticket. You can use it all day long.
3. Main Street...Walk through the shops to get either out of the park or in when there's a lot of traffic or a parade going on.
4. Break in Honor of Bawb...Enough said.
5. EMH (at night)...I can't speak enough about this. Utilize the extra late Extra Magic Hours (think midnight at Epcot or until 3 am at Magic Kingdom). They are golden during peak season with little to no wait. I relax in the morning and get most attractions done during these. They are best during peak season because they are so late as compared to those held during regular or off-peak times during the year when they become crowded.
6. Use Foursquare and FB...Use your iPhone to track your trip. It's really a fun enhancement.
7. Kim Possible...Make sure you and Stella save the world over at Epcot! It's a fun break from the hectics of the parks!
8. Slow Down and HAVE FUN!
