One thing to be aware of at the MK restaurants for those early reservations. When the place first opens at around 0800, they are swamped with guests, and truth be told, they don't worry much about whether your reservation is for 0805, 0810, 0815, 0820, or even 0825. They want to get guests in and seated and get the restaurant flowing.
The result is that at that hour, what time you get seated depends a lot more on where you are in line to check in than what time your actual reservation is for. No one comes out and says "who has an 0805? Step right to the front! All the 0810 people come over here. 0815, relax and we'll get to you in just a few minutes . You 0820 folks, don't even think about it! . . . . "
It might sound unfair, but my observation is that it's like that every time I go to CRT or CP. Later in the day, once things are settled, there's more structure to the operation.
