Thanks guys for the help!

For Sheraton and HI, if I cancel, the points come back. HI via the website, Sheraton by calling. For Hilton, once the certificate is made, I have a big process to get them back, or use the cert at a different date.

Just needed to know, I'll get a certificate as I plan to stay at the hotel for the date I booked.

Oh yes, no CAT 1 PS this year. Probably never again. Bad idea Hilton, but I'll still stay with Hilton because me likes breakfast!
