What Have I Done Now?

In three weeks, I will be taking the family to Disneyworld.  My dad is taking us all expenses paid.  All I have to do is get my family from Tennessee to Florida.  My plan was to drive stopping in Atlanta and spending a night with my sister and her family.  Seemed like a good plan to me.  Then my wife started whining about flying.  Now I am not scared of flying.  In fact, as a child, I flew quite often.  Parents were footing the bill then.  I don't think I have flown in 25 years or more.  I was a little nervous because I am a big guy.  I hear all the time from friends that fly just how small planes and the seats are.  My wife found a flight down for $29 (bs, but more on that later).  I decided to research things.  Turns out the seats are 17.8" wide.  My desk chair is 21" and it is okay.  I could probably go 20" and be good.  Anything smaller and I don't know that I will fit.  You must be able to lower the arm rest completely.  I am not sure how to measure my ass but I can tell you that it is bigger than 17.8"  Here is my thinking.  I will be sitting next to a 5 year old or a 6 year old.  They don't need there entire 17.8".  I hope I will be allowed to borrow a couple of inches from them.  Does this sound doable?  Also, I got to figuring.  The $29 flight starts adding up.  $29 x 4 people turns into $320 after all their little fees are included.  The good news is it is only $310 to come back home.  So now, not only am I spending $630 flying to Disney, I am not even sure I will fit into the plane. 

To top it all off, I could care less about Disney.  I hate stuff like this.  Somebody convince me that it isn't that bad.
