I am a PP with marriott and diamond with HH only out of necessity. If marriott would be where I go 100000% of the time, I woiuld never stay anywhere else. I have been lucky to have had onlt 2 stays in HH in the past 5 months, as business changes have enabled me to stay almost exclusively @ marriotts.

To me, the downside is if plans change and no marriott property, then you will have no ststus to fall back on w/ the different program.

To me, the travel packages rock!!
