When planning a cocktail style event, there are a few key things to keep in mind:

1. Guest count: Determine the number of guests you expect to attend and plan accordingly.
2. Venue: Choose a venue that is appropriate for the number of guests and has a suitable layout for a cocktail style event.
3. Food and drinks: Plan a menu that includes a variety of small bites and hors d'oeuvres, as well as a selection of cocktails and non-alcoholic drinks.
4. Entertainment: Consider hiring a band or DJ to provide music, or consider other types of entertainment such as a photo booth or a magician.
5. Staffing: Plan to have enough staff on hand to serve food and drinks, as well as to manage the flow of guests.
6. Decorations: Consider the theme and atmosphere you want to create, and decorate the venue accordingly.
7. Timing: Plan for the event to last about 2-3 hours, with peak activity during the first hour and a half.
8. Finally, don't forget to send out invitations and track RSVPs to ensure an accurate headcount for the event.
