Thanks for the suggestions all... it is business related, so I don't have a fixed cost, thus the reason for not giving a set dollar amount. The XNA route is normally around $600 minimum these days if I'm lucky. Most of the time, on short notice, I'm hitting $800-$1000... and that's standard 4 segments. Just figured I had a little time to plan these, so I'm hoping I can get creative and get the additional segments.
And MSPEconomist, point well taken as to changes/etc shaking up the agenda. I'll keep that in mind in routing. I'm playing with ITA now to see what I might concoct.
