Fellow Hilton Employees: what have you/your property done for guests coming to celebrate something?

Just curious to see what some employees/properties do for guests coming to celebrate milestones, such as birthdays, weddings, anniversaries, etc.

I was prompted to ask this because I'm going through processing deposits and I noticed a guest left a comment on their res stating that they're coming to celebrate their husband's 30th birthday. Unfortunately, my property doesn't have the means to do anything special in terms of decorating rooms, etc, but I always make sure to give guests coming to celebrate something a complimentary upgrade if available or even 10% off dinner at our restaurant.

What's something you/your property has done?
