Although Hilton's Walk for Hope promotion started last Fall, they certainly added value this year by allowing registration of another "virtual" walker. I think we did 2 walks in the Spring and we have another 3 coming up.
And I'm surprised no one has mentioned Hilton's ill-fated CTCH promotion. Say what you will about their after-the-fact audits that yanked it back for those who didn't qualify (and much has been said)- I think the people on this Board got a lot of benefits while it lasted.
Finally, DL's "dash to the gate" points were welcome since they alleviated some of the "sticker shock" when I tried to book MCI-MYR for 3 people over Christmas this year ($500/person RT compared to $20-300 in prior years). Those points gave me enough to get my son a free ticket.
