The problem is that the boat can be full of FW guest by the time it reaches the WL.
I can't even begin to remember when the boats went to FW before WL or vice versa. What I can tell you is that even at one of the absolutely busiest times of year, we never once encountered a boat coming or going from the WL that was too full to accomodate all the WL guests waiting to board. We were there from 12/19/02-01/01/03 and it never happened, even during the busiest part of our stay.
Just a thought....
Weeks before our Christmas trip, there was a thread where there were several complaints about how slow the transportation was from WL. Chip n Dale suggested that perhaps it just "seemed" like it took a long time, when in reality if you were watching the clock and timing it, it wasn't really all that slow.
I decided to do just that. Every time we used the busses, I noted the time on my watch. I can tell you that it never took longer than 5 minutes for a bus to arrive, most times there was no wait at all as there was a bus sitting there when we walked up.
It's funny though, once just a day or so before Christmas, we walked to the bus stop to go to either the AK or DTD, I don't recall which now. There were perhaps 20 or so people in total waiting for busses to somewhere. On the phone to the WL desk was an irate guest who was ranting and raving rather loudly about how long he had been waiting for an AK bus. There were a number of other guests that were complaining to each other as well. According to him, no bus to anywhere had shown up in over 45 minutes (some were saying over an hour) and he was demanding that they get a bus there.
Two things....1) At that time of year, if no bus had been there for 45 minutes, there would have been a heck of a lot more than 20 people there and 2) Within 3 minutes of us walking up, there was a bus to the AK with other busses getting there sooner than that. The gentlemen complaining almost missed it because he was on the phone complaining.
Timing the wait was a great suggestion. It's amazing just how long a short wait can seem when you're anxious to get to the parks!
