Each trip has been different from the next. My sister is a cheerleader and my first 3 trips we didn't officially know we were going until a week before the trip so we kinda made them each a little different. We would spend a whole week, giving one day for each park, one day for cheer comp and then one day for a non-disney park, EX: Universal Studios, Sea World, Discovery Cove...It made our trips even more amazing.
My most recent trip to WDW we only had 3 days to take on all 4 parks, my mom and I managed to hit all 4 parks plus the firework shows in 48hours. We had to choose what we wanted to do and what we wanted to miss. It was the most fun I have ever had. My mom and I spent our last day lounging in our room and had a leisurely dinner in Magic Kingdom, plopped our butts down on this bench in front of the castle, for probably 3 hours and watched the electrical parade, magic memories and you, plus the fireworks. We then went skipping through frotierland, yes skipping my mom heard the music from the 2nd electrical parade showing and decided she wanted to frolick, and it was the best.
