The MK Jungle Cruise signage may be more intrusive, but its infinitely clearer to see, in very short order and from a greater distance, where the different entry points are located. The DL Jungle Cruise entrance is beautiful (much more so than the MK entrance - period) but it takes one more time and to be closer to the attraction to figure out where they need to be.
As for having a CM stationed out front, in theory this works but in practical terms it begins to fall apart:
- First, you have to either find the CM or be able to hear him or her/make out what is being said, a task that is not so easy to do if there is a crowd milling around the entrance area.
- Second, what if the CM is answering another guest's question? Taking time to help this one guest prevents him/her from being able to make general announcements on where the entrances are located. Or it results in a line of people waiting to ask where the line is, as the CM can only talk to one group at a time.
- Third, there is a language barrier. Considering the high foreign number of foreign visitors who come to WDW, having someone giving directions in English is not going to help a significant number of guests and may just cause more confusion.
As for smaller signs, yes they could be smaller, but the point of these signs is to help people navigate their way from a distance BEFORE they get to the gate. This prevents people crowding around and blocking the entrance while they try to read the signs at the last minute. As for less intrusive signs (like on the pillars perhaps?) if they were located there they could easily be hidden by someone standing in front of them.
As I said in an earlier post, there may be disagreement on some of the details, but the practical reasons for these signs are justified.
