Hi Newbie,
I've met her a few times.
I would say whatever I have requested for, is the usual "standard" requests, e.g. increase in parking & invitations, (free flow beer not incl. cos i was told not their hotel policy, i think it was stated in some of the earlier posts in this thread so I didn't try to pursue any further on this) and she did it for me.
I suppose they are prepared to give u all these since it's quite "standard" other hotels would accommodate to when requested upon.
As for other requests, like anniversary stay, I haven't tried it yet. My sister is encouraging me to ask for this. Let me know if you managed to get it yea~ (via PM also can, if u are more comfortable that way).
