I know what you mean and I would not trade the 45 min. hassle of parking at the TTC (this is required only when you don't have a bus option while staying onsite) for some brief monorail magic. I would reserve that monorail ride to get to and from CM in the middle of the afternoon and not try it at opening or closing with everyone else from the TTC.
I consider the TTC to be a traffic engineering nightmare and one that you will not "miss" but may only be convinced having experienced it. I consider it to be a tragic beginning and ending to an otherwise wonderful day.
Others on here would tell you how wonderful going thru pay parking lines (although onsite guests don't have to pay they still have to wait in line), parking in throngs, waiting for a tram (to take you to the monorail), waiting in line for the monorail, riding the rail, then getting in line at a ticket turnstile, only to do it all again in reverse when leaving is. But, I simply don't agree and only do it when absolutely necessary (staying off site). Even Disney realized the ridiculous set up and hasn't copied this traffic nightmare for ANY of it's subsequent parks. Sorry for the rant but you can see I really don't enjoy TTC and think you would prefer the bus dropping you off near the MK ticket turnstiles and saving the monorail for your afternoon enjoyment.
