Like everyone says, a lot depends on speed, weather, etc. My 2 cents:

Plan and file conservatively. IFR alternates + 30 extra minutes for Momma
if IMC is out there. Then fly the plan until you know better. There's
plenty of time to amend, re-fold charts, and examine price lists if you
decide to fly a longer leg.

OTOH, If IMC operations are involved, forget the price list and make all
airborne plans based on range, capability, and critical facilities (weather,
runway length, ILS....possibly fuel availibility - fuel price doesn't even
figure in at that point). You don't want to compromise the flight and your
safety to save $1 a gallon

Get and use some sort of range extender. As mentioned, Little John is fine,
baggies if you can handle them (tampons help), absorbent gels in a bag seem
the best to me. Even if you are determined to land to pee, have a backup.
Nothing worse than squeezing you legs together and having your eyes tear up
while on extended downwind to Runway 10,000' at Long Walk International.

I am filing a flight plan 750 NM.
I have 3 fuel stops appr venly spaced. I have 48 gallon usable and burn 11
gph.
I could make this trip with only 2 stops, but choose 3. I save about
$100.00 by
landing at places where fuel is less that the big airports.
Many of my pilot friends tell me that I am crazy (which may be) Once
airborne
they tell me they do not land unless they need fuel.
What is you opinion? Am I to frugual or conservative.
