We've experienced both before and after, in terms of construction. The difference between last December and the end of August were impressive. I was expecting a horror show in Sugust,based on last December and it was just the opposite.
I recommend you chose the Lime garage as opposed to the Orange,as it's more centrally located. As you approach it,there are two lanes. I'm pretty sure you should do the left lane and head towards the second level. We found out that is the most popular level because it's the one everyone had to gravitate to to get out of there. You have stairs or elevators that take you to the one escalator that drops you in front of the fountain,a great landmark for finding your way back. Getting in and out is just easier from the second level. Took us a few visits to figure that out. It's also why that level runs out of spaces before the other levels. There are lights on the ceiling at the end of each row, telling you how many spaces are available in that row,although we found the accuracy to be somewhat inconsistent. Over the course of a week,we found it to be easier and quicker to drive there than take transportation( we stayed at the WL). It took FOREVER for a bus to show up to take us back to the resort. It was that way with all the resorts. You will wait at least 25-35 minutes for a bus back,sometimes longer. At least,that's how it was for us. Driving back and forth and using the garage was so much easier !
