OK, I finally got thru today and Felicia said there was only one reservation left, so I only got one reservation for myself.

It really does work. Submit it, you get an e-mail in a day or two, done, one way or the
other. I make about 20 reservations a year this way. The process has never been a
problem (there was one time that there was an oops (they gave two people the same
reservation number, and the second people (not me) was what was on the roster. But
that could happen with a telephone call too, and Ranger Chuck straightened it all out,
and I got OOOPS e-mail Monday.
