We used to start out with POTC, but lately they seem to be opening that Adventureland later, so now we head directly to Buzz. We either get fastpasses, or wait in line (my rule of thumb is to wait in line if the wait-time is 30 minutes or less). Buzz is my fave, but DH is not a big fan (probably because I can beat him). DH also refuses to do SM...if we are with other people we go there next, if not, we head over to Fantasyland and get fastpasses or wait in line for Philharmagic and/or Peter Pan.
HM is next, then we do the twin peaks (DH will do Splash if it's hot out).
We round out by hitting POTC, then we go around again and hit anything else that strikes our fancy...and shop and eat!
