Event411.com, an online event registration service, has acquired Meet UP.com, a Vancouver, B.C.-based online housing reservation and hotel block management service, giving event organizers complete registration capabilities.

Steven Koltai, Event411's chairman and CEO, announced the news at the recent Incentive Travel & Meeting Executives Show in Chicago and rolled out PremierPlanner 2.5, an updated version of Event411's invitation software. PremierPlanner 2.5 "delivers robust new features, including planner-defined online registration forms, in-depth reporting tools, attendee profiling, targeted e-mail marketing, the ability to create custom Web sites, and a streamlined interface for planners to navigate through the tools," says Koltai. "We've invested $3 million in this product."

Event411 offers sophisticated planning, registration, messaging, and to-do list functions tailored to the professional meeting planner. Too complex for you? A project manager and client services rep will walk you through your first event.

With the purchase of MeetUP.com, Event411 now gives meeting attendees the ability to log on and compare room prices, amenities, and real-time availability of blocked hotel rooms, and to book, modify, or cancel room reservations at the hotel of their choice 24/7.
