Hospitality Events & Sales enticement sample writing

I need a few samples of what one would write to exisiting customers, current customers, and potential new ones to entice their business, thank them for their business etc for a hospitality event & sales for a hotel or an event group for their group events (talk about all groups-- sports, conventions, weddings, reunions etc)

also marketing aspects/approaches

im looking for quality not quantity

i'm looking for around 3 samples to show off different styles/enticements/approaches etc

i want something that draws them in and keeps them reading then just a long list of what "we can do" but nothing flashy like HUGE BOLD FONT.

need this asap
