Don't use the monorail for early morning entries. They will not let you enter the monorail until the park opens. We wasted 20 minutes of our early hour just riding the monorail. The next early morning entry we entered the park at the gate and got to ride nemo within hte first 15 mins. The walk from DLH is really not that far to the maingate. The walk takes you through DTD, so it is not boring.
We love ataying at the DLH and can't wait until we are back next weekend.
