Hilton HHonors - Rate Plan Codes for Hilton

Hi Gang:

I see this thread on the rate code LVO:

But I do not see any other threads on the usual rate codes for stays at Hilton and other HHONORS properties.

Below are some that I have recently encountered -- does anyone know what they stand for?

LVO = Rack Rate?

L-48 = ??

L-H0 = ??

C-VUP = ??

Thanks in advance and feel free to add other rate codes that you have encountered.

In my experience, corporate and travel agency codes for Hilton are several digits long.

I have used certs from the Hilton Diamond Club (which is a paid Asian membership program). These codes are more like what you have listed, but cannot be booked online.
