Is there supposed to be some advantage to entering AK this way?
If so, I don't know what it could be, except if your were planning to visit Rainforest Cafe anyway.
This entrance might be less crowded, but it is also out of the way. If you were trying to get up front for rope drop, it wouldn't make sense to enter this way. If you are trying to avoid a crowd entering the park, you are walking quite a distance to do that, and if it is crowded, it is likely that the gift shop that you have to walk through to get to the entrance will be crowded, too.
