We first visited in the early 70's. Just the wife and I, (Tix were $23.) We stayed from rope drop until late, we would watch fireworks from the exit plaza , then beat the crowd to the car.
After 2 kids, we made the family trip from NY every year for 25 years in a row. With kids we did rope drop, but added the mid day resort pool break, then back to the parks.
When the kids were old enough, we became Disney Commandos, MGM Studios was now open and we would Hop to all 3 parks in a day. (Hopping was free then). When AK opened we Hopped all 4.
Now we are in our 60's and we have slowed way down. We have retired and moved to Central Florida. Having visited so many times, on our next visit we will hit the new stuff (Pandora, Star Wars) and then see what we can, no hurry.
