Pardon my ignorance, but we have never flown before and actually have never even been to an airport. I was shocked to look on the website for MCO and find how huge that place is. So, I was wondering, I assume that if I get to my airport early, I can enjoy all of the shops and restaurants. When do you check in? Is there a certain time? When do you go through security, or is that the same thing? After security, is there a holding area for passengers? I assume that you couldn't go back out to the shops after that. Sorry if this seems like a silly question, but thanks for your help!!!
