How long does it take to see an entire Disney Park?

I will be spending some time in Orlando, FL this fall and I plan to visit all 4 Disney Parks (Magic Kingdom, Epcot, Hollywood Studios, and Animal Kingdon). I will also visit Universal Studios in Orlando. If I dedicate one full day to each park, would that be too much time or too little time to participate in at least 95% of the attractions?How long does it take to see an entire Disney Park?
well this is what i would recommend for those parks....

-magic kingdom: 2 days (you can get most things done in 1 day if you get there early and rush)

-epcot: 1 to 1-1/2 days (can be done in 1 day if you skip some of the smaller things but if you want an indepth experience i would definitely go to the 1-1/2 days)

-hollywood studios: 1 day (can easily be done in 1 full day)

-animal kingdom: 1/2-3/4 of a day (can easily be done in 3/4 of a day)

-universal studios **JUST UNIVERSAL STUDIOS AND NOT INCLUDING ISLANDS OF ADVENTURE**: 1 day (can easliy be done in 1 full day)
Okay, if you're going in on weekend days, lines are longer. Magic Kingdom and Epcot take more than one day for doing all the attractions due to amount of them. Hollywood Studios will take longer than one day because of line length on the main attractions (tower of terror, rock'n'roller coaster and midway mania). Animal Kingom could take any amount of time because you never know what amazing animal you could see there. I'd give 6 days for Disney.How long does it take to see an entire Disney Park?
it all depends on the lines for magic kingdom and epcot you will need longer than a day

and animal kingdom they close early because of the animals so most likely a day and a half and Hollywood studios you will need just about a day
I rode 18 rides in all four parks in 1 day from opening to closing so it is possible and we didn't have to sprint to the rides or anythingHow long does it take to see an entire Disney Park?
EPCOT may take longer than one full day. And it will depend on the lines. We needed two days per park.
You will need much more then 1 day for each.

I know people that have been there for a week and couldn't see it all.
Indiana Jones really knows what she's talking about. She's got great advice on WDW. I totally agree.
