Thanks, tinkybelle, I'll keep an eye on my number.

Too late, GUWonder. NW already has my number on file. As for upgrades, I figure if I'm not upgraded by or at check-in, I'll just go ahead and make the FF program change then.

I may end up having to do this anyway, satori!
Thanks, all, for your input. ^
