So from what I am hearing there is a res line for diamond that will be more helpful than gold. = worth it.
Also, it seems that Hilton is a bit picky for "executive level" (though I haven't had a problem) = worth it.
Finally there are more bonus points available as diamond. = worth it.
I have a week scheduled in March so if I make diamond at the end of Feb. I can reap some benefit. Thanks gang.
