Maybe it's just me but this pattern seems a bit odd:

Checked the Residence Inn Savannah Downtown for 2 nights in April, and there is absolutely no availability for a Thursday, Friday or Saturday check-in from 4/3 - 5/24, yet every single Sunday-Wednesday is available.

But the SHS is wide open from 4/10 on. Are there really that many people trying to save 5,000 points a night (edit: or use Cat 5 certificates, as it's really the only one in the downtown area)?
