I thought I should share my recent HHonors/DC experiences.

Last month I had a reservation at a Homewood Suites; at booking I set my mile-earning preference to Southwest Airlines. At check-in I was able to give my 11-digit DC# to the clerk; I received DC credit for this stay on the most recent HH sweep to DC (5 July).

I am certain that in the past I have successfully used my full DC# when booking Hilton family reservations online. However, for the last couple of months I have been unable to use my 11-digit DC# when making a reservation at Hilton websites. Finally I got tired of this and called the Hilton Diamond Desk yesterday. After being able to replicate the error, the rep I spoke to put me on hold to check with their "airline liaison". Eventually he came back & said that 8-digit numbers appeared to work. For now he created a # for me by dropping the first three zeroes from my DC#, but he also put in a query to try to figure out what the DC# problem is.

I will post back if I hear more.
