We have done 4 parks in one day TWICE
The first time my kids were little and we only had epcot left for our last day. We asked the kids what they wanted to do before we left...MISTAKE.
We ended up revisiting FAvorites in the other 3 parks and ending at Epcot.
In AK all we did was see the Festival of the Lion King. Yes 15 years later, they still say...remember when we visited ALL the parks in one day!
In Feb, I was on a girls weekend. I mention the above story and my friend said, I want to do that!
We started by walking to HS, we got a bottle of water (so we drank or ate in all 4 parks too!) did the character drawing and left the park. We had to meet a girlfriend who was leaving that day. We then walked to the back entrance of Epcot. Had an adult beverage and lunch in Italy. We walked to the front of the park and got onto the Bus to AK. We watched the afternoon parade, rode the Safari, ate Mickey Bars.
We caught a bus to MK. We got Mickey Pretzels for "dinner" We saw the parade from the Hub, turned around watched wishes, decided we were exhausted...walked out and saw the water parade. Thought, this is crazy, it is a beautiful night and everyone is leaving this park and it is open for 3 more hours (EMH). We walked back in, sat on the rocking chairs at Tony's, got our second wind and stayed til 1:00 am. Inthose last few hours, we rode Little MErmaid (twice withpout getting off), Buzz (twice without getting off) Pooh, Dumbo (twice without getting off) Carousel, and we saw 4 Princesses at in Fantasyland in about 5 minutes!!
It was the PERFECT day! lol!!
Of course I texted hubby saying, "I did 4 Princesses in 5 minutes!" The response I got "I'd like to do 4 Princesses in 5 minutes!"
Good Luck and Have Fun!
