I was wondering about this. I know when Indy was added and the Jungle Cruise boathouse was built... things got crowded. A lot of it was, and continues to be the popularity of Indy. However I was thinking about something else as well. The Boathouse is actually CLOSER to the Jungle then the previous hut was, which means they did make an attempt to expand the street. Aside from the planters I can't figure out why it always seems so crowded. Indy is a chokepoint, and you expect that hassle at the end, but it always seems so crowded ALL OVER and not just there. Did the old Adventureland have these planters, was it this crowded, and was it as built up?
