From DLH, the parks are a short nice walk through DTD. We really enjoy that walk. As far as the monorail, it is more of a ride then real transportation at DL. Also, unlike at WDW where the monorail drops you off at the front of the park at DLR, the monorail drops you off in the back of Tomorrowland. You definitely don't want to do that on your first day unless you don't care about that morning walk down Main Street seeing the castle. We usually stay at DLH, and we typically only use the monorail if 1) we just want to ride it; 2) we want to get to Tomorrowland first; or 3) we are in the Tomorrowland area and want to go back to the resort and don't intend to browse or stop anywhere in DTD. I think it is about a 10 minute walk from DLH to the park gates. DH got so irritated with me one day because I wanted to ride the monorail and there was a line and I think we waited 20 minutes for the monorail- he kept telling me how we could have been already been back at the resort as we were waiting on the monorail! As far as CA, in the mornings you definitely want to do the main park gate if you want to be toward the front of the rope drop crowd. I also don't think it is really that much faster to use the GC gate to and from DLH by the time you wind through the resort and back out to DTD unless you are specifically going to or coming from something on that side of CA. If we are in that area of CA at a time we plan to go back to the resort we use it, or if we happen to be in the GC or are planning to go somewhere near that entrance first, we use it. We typically time Grizzly River Run for a time we are going to the DLH pool for some swim time, or a time when we can go change clothes if we want and we use that exit to head back to the DLH when we are soaked!
