Embodiments of the present invention provide a system and method for collaboratively planning an event via a collaborative event planning application. The collaborative event planning application may be accessed via user terminals connected to a network such as the Internet. Individual aspects such as theme, date, location, attire, travel, and lodging pertinent to the event and group discussion may be edited by a host, designated co-hosts, and invitees. Hosts and invitees may also make decisions regarding the event by voting. The collaborative event planning application may also periodically suggest vendors and provide notifications and recommendations based on the event details and preferences of the users.
