I would have to say that if you hit Fantasyland first, you should be alright, maybe get a FP for Space Mtn first, just to assure yourself a shorter wait for it. COP is pretty much a walk right on ride. It is a classic, but it isn't appreciated by everyone that goes to MK. I've never had a long wait for HM, I just normally go to Frontierland first, then head over to HM then Fantasyland. I like to get Thunder/Splash Mtn out of the way early. We still get some decent wait times for Fantasyland (we try to go on days that don't have EMH). But for you, I would get Fantasyland out of the way. Maybe get in line for dumbo after getting a FP for Pooh. Then when that window opens, get one for Buzz, and I will tell you why to get one for Buzz before Space Mtn. First, it depends on how long the wait for Space Mtn is, and how long before the window opens for a FP from Space Mtn. But normally the wait for the window to a fp to open for Buzz isn't very long, and you could ride pooh, philharmagic, and maybe Peter Pan (this ride normally is one of the longest waits in Fantasyland, so you might need a FP for that ride also) by the time the window opens for Buzz. At that point, get a FP for Space Mtn, ride Buzz and COP, maybe hit some of the other rides you didn't get to first, and then come back for that Space Mtn FP window. I hope that that isn't too confusing. It normally includes quite of bit of backtracking, but if you have just one person getting the fastpasses, then it makes it a little bit easier (in my group that person is me, can you believe it?)
