Well, for myself, standard at GCH is my preferred booking. I've had every kind of room but for me, I simply want a room near the lobby/elevators. The view isn't good enough from the other tiers to justify the expense for myself. I rarely spend much time in the room. We did enjoy the courtyard view when our kids were little because they liked watching the monorail go by, but it honestly depends on how much time you spend there. I love having a room right off the lobby. Having a room close to elevators is also a key item for me.
It used to be that there were hotel discounts offered during the holidays and the standard rooms often weren't included, so I'd already have a standard room booked and when the discount came out, I'd call and switch to a courtyard room and still save money. I still requested something near an elevator. Last year we got a super cool room on the 4th floor just past the main elevators if you turned to the right. One floor down was the large sitting area where I *think* the concierge desk is. That was awesome, as we had a great get-together there with our friends and exchanged Christmas gifts and had some goodies. I'd love to get that room again this year or the same room one floor down.
One of the worst rooms I ever had was in the DVC wing (we weren't DVC) right in front of Goofy's Sky School or whatever it's called. It was so far away and had a VERY annoying light that swung back and forth from the ride and shone right into our room.
Good luck!
