Re: breakfast - I stopped at Ike's not too long ago. I was connecting off of a redeye from SFO. Not great food, but not bad, and it was open at 6a. I dropped a business card in the fish bowl - didn't win anything, but they actually sent me a card thanking me for my visit. I was extremely impressed by that gesture, so personally, I would say that yes, get to the airport early, and if you have time left over, grab some breakfast. Missing your flight to FLL is going to get your vacation off to a bad start.

Absolutely no disrespect meant to @SchmutzigMSP, and I know MSP is your home airport, but I've just seen such huge variance that I personally wouldn't chance it. My home airport used to be DTW, and I used to cut it close, and even with the elite lines (which OP cannot use), every once and a while crap happens. You get a "behavioral specialist" who thinks you deserve the works, the guy in front of you throws off the alarm three times, the agent makes a red diagonal line across your BP because you were the 7th pax after their last sip of coffee, who knows. I agree that most of the time you're probably fine, but the question is if you're starting (or ending) a vacation, is it really worth saving a half hour to risk it?
