Don't pay any attention to anyone except you. If you are more
comfortable stopping more often, do it! There's a lot of things
my airplane "can do" and "is allowed to do" that I won't.

Personally, my rear end doesn't like being strapped in more than
2.5 hours. I can make it to 3 but only if absolutely necessary.

Besides, cheaper fuel is good. Never having to say "I'm Sorry"
because you ran out of fuel with the airport in sight is
*really* good!
