Blog Poll: Which would you prefer?

A little background first.  We are going on vacation soon with two other families to Florida.  We drive because it's only 12 hours and flights for 4 people are outrageous.  Not to mention how much crap you need to bring to a beach house for a week with kids.  Chris found out a few weeks ago that he had a conference the week before our vacation, and would be flying home the day we are leaving.  This made me nervous, because we would have to leave a few hours later than originally planned, and if his flight was delayed or canceled, the kids and I are stuck waiting for him to get on the road (i.e. I am stuck with two anxious preschoolers who want to be at the beach!).  I suggested he find an airport on the way down so we can just pick him up on the way.  He found a flight that works perfectly with the travel schedule.  And if something happens with his flight, we are more than half way to our destination, and the kids and I will just get a hotel room for the night.  I will be driving the kids 7 1/2 hours by myself before we pick Chris up at the airport to finish out the trip.  Reminder my kids are almost 5 yrs girl and almost 4 yrs boy.

Now Chris was relaying this plan to his sister last week, and she thinks I'm crazy (and can't believe I agreed to this).  A little background on her.  She lives in Houston, and has 3 kids: 3 yr boy, 4 1/2 yr girl and 7 yr boy.  Due to the high costs of flights, this year she and her husband are driving from Houston to upstate New York (28+ hours) this summer with the kids for vacation.  They figure it'll take 3 days (each way). (one way ticket to the loony bin anyone??)

Chris's sister told him she would rather drive 3 days with her kids and her husband, than drive 7 hours with her kids by herself.  I'm curious what others think.
 
So which would you prefer 7 hours by yourself, or 28+ hours with your significant other?? (I know most would say NEITHER!!!!, but it's my poll, and that's not an option!)
