There is a lot of debate on that one. The standby lines at DCA for TSMM do tend to be much shorter than at DHS. Some will say that the FP at DHS
causes the standby to be much longer. In any case TSMM is one of the harder rides to do at DLR without a longish wait. It is hard to get on first thing in the morning without sacrificing other things. Fortunately it has the strange pattern that the line
decreases throughout the day after a surge in the morning.
If you can handle the single rider line that is the way to go IMO.
Some have taken the lack of FP on TSMM to mean that DLR has decided to start scaling back on FP. For example, there are two major rides coming to DLR in the next few years. A "dark ride" called Voyage of the Little Mermaid in 2011, and then a Test Track type ride called Radiator Springs Racers. The rumor is that neither will have FP.
Along these lines, if you are inclined to delay your trip another year (or two) DCA will be seeing lots of new things. Disney is investing an unprecedented $1 billion to upgrade the entire park. For more info see
