Trouble in Florida

"I'm sorry the business part of the trip went so badly," I told Mike as we dashed in and out of traffic on our way to the airport. We had spent three stressful days in Florida attempting to complete some business, which ended up being a complete waste of time and effort.
"It's okay," he mumbled, still recovering. "At least we were treated to a theme park. It still makes me laugh that you chose Harry Potter."
"OH MY GOSH, it was one of the best days of my life!"
"You were like a twelve-year-old."
"Thanks for buying me a wand."
"Like I could resist after seeing how giddy you were."
"Do we have to fill the car with gas before turning it back in?"
"Yeah, but we are really pushing it time-wise. If we miss our flight, I might actually sit on the floor and cry."

"There is supposed to be a gas station at the next exit."

There wasn't. And the exit took us ten minutes out of our way before we were able to point our car toward the airport and drive as if we were competing for a NASCAR championship.

"Can you check my emails?" Mike asked handing me his phone. "I don't think I got the usual email reminding us of the departure time, so maybe we leave later than I thought."

I looked at the screen and then I rubbed my eyes and looked again. My mouth formed words, but no sound came out.

"What's wrong?" Mike asked. "Did we miss it? Are we too late?"
"What is the date?" I whispered.
"July 30th."
"In that case, we are two hours and seven days early." I tried not to laugh, but I couldn't help it.
"What?"
"It says our departure is for the same time we thought, but on August 6th."
"What?"
"We totally should have gotten a multiple day pass to Harry Potter."
