My usual practice is to set up two in house servers, each of which 
talks to:

time.windows.com
time.apple.com
and one of the NIST servers

0.us.pool.ntp.org
1.us.pool.ntp.org
2.us.pool.ntp.org

and each other. 

And then point everyone in house to both of them, assuming they accept
multiple server names.

But I am young, and not much travelled.  :-)
