There is definitely construction between Champions Gate and the Disney exits. There is usually congestion heading Eastbound at the entrace to I-4 as the bridge is where there is currently a lane drop. They are working on expanding I-4 to three lanes right at Champions Gate right now.
It took us over 40 minutes to get to Celebration this past weekend. Granted, it was at night, but it is only 4 miles.
Going to WDW should not be a problem, but it pays to know your options when the parks close and I-4 Westbound gets busy.
If you are not going to be coming to the area for a couple months, you should be OK to take I-4. But the 192 construction will still be going on. It would be best to take the first Disney exit (62) and not try to make it up to another exit.
If you are going to AKL or AK, head out of the Omni, go up through Champions Gate Boulevard and continue up the hill past the I-4 interchange. At the top of the hill, you will come to a stop light. Turn left onto Old Lake Wilson Road/CR 545. Take this through the newly build hills of Reunion. This will take you up to 192. As you get up towards 192, stay in the right hand left turning lane (got it?). Turn left onto 192 and then get into the far right lane. The next light will be Sherberth Road. Turn roght onto Sherberth. As you head down here, you will see a pasture and across that, you will see Expedition Everest looming over the treeline. At the end of this road, get in the right lane. You will come to a light. This is the Osceola Parkway. Left goes to AKL, straight goes backstage, and right takes you towards the rest of Disney property. AK is just a short distance down on the left. Since this is divided, be careful and catch the first turn-around to get to AK. Otherwise, continue down the Parkway and follow the purple signs to your destination.
This is a great "back way". I do not call it a shortcut anymore as Reunion is increasing the traffic on 545 and I-4 is going to be better once the third lane opens.
