The ultimate dark rides (POTC and HM), the ultimate Tomorrowland, a brand spanking new NOS, Mine Trains and Pack Mules, studio animators offering free sketches, the original Golden Horseshoe Review, it's gotta be the 1960's.
Maybe because I was looking through the magic of my Childhood, but my favorite decade was the 1980's.
You still had a lot of Walt's ideas in the park, but a resurgence of technology to bring about rides like Star Tours. Later in the decade things got bad, but for the most part you had the best of the new and the best of the old combining to make a really magical experience!

Maybe for once, someone will call me "Sir" without saying, "You're making a scene!"
yeah i had a real hard time naming the thread and trying to word the question right
In that case, I'd probably vote 1985-1995, or the 1980s if I have to stick to a calendar decade. That certainly wasn't the most phenomenal time for new additions, but the whole park has probably never been better. It was before Pressler-era neglect and poor decision-making really settled in, and all of the currently existing classics were already there or were built during that time.
But most of you seem to be responding to the other interpretation of the question. If that's what we're talking about, I'd probably pick the 60s, or the '59-'69 decade mentioned by others. That's a harder decision, because a lot of great stuff was built throughout the park's first four decades ('55-'95), but that time period was just so saturated with the construction of essential Disney attractions.
