916chipndale has the stop order right, including DTD.
And yes, there are times when a bus may fill up before reaching GF and skip the stop. If you don't mind getting started 45 minutes earlier and you absolutely want to be at the park by rope drop, boarding at the CR wouldn't hurt.
I say 45 minutes based on 30 minutes to get from GF to CR (including wait time for the monorail), 5 minutes to walk from the monorail platform to the bus stop, and 10 minutes extra time on the bus since it will be stopping at Poly and GF on the way.
Or, you could just be at the GF stop 25 minutes earlier, and hang around outside DHS until the gate opens. Hopefully, 2 buses in a row won't skip GF, or if they do, some one will be on the ball enough to send an extra bus.
