I have been at WDW for 2 days on two different trips years ago. A four day trip 10 years ago. Since then I have stayed no less than 12 days and up to 28 days. I have never been bored and have always had a great time. What changed over the years? Lots of hard work and going up the career ladder. All college education paid for. Retirement. And became DVC members. The 18, 24, and 28 day trips were different than the 12 to 14 day trips. Lots of r and r and "missing" the Lake Erie snowstorms.
