Leaner and Meaner in 2018!

This year we make the conference leaner by squeezing it into two (2) days of meetings on Wed and Thu 06-07Jun18. There will be two (2) half-days of closed User session and two (2) half-days of closed Siemens and User session. Vendor Exhibition will be Wed afternoon and evening.

The 2018 Annual Conference will be held at Chateau on the Lake in Branson, MO. It is a stunning property on beautiful, pristine Table Rock Lake. The Chateau is every bit as distinctively impressive today as it was when we last visited in 2005. I also secured the same sleeping room rate of $179/nt as we had back then. Note our group rate will be honored two (2) days pre- and post-event based on availability.

For your travel planning, most folks will fly into Springfield-Branson National Airport (SGF). Drive time from SGF to Chateau will be about an hour. Another option is to fly into Branson Airport (BKG). Drive time from BKG to Chateau is about 25 minutes.

Please reserve your hotel room now, especially if you are considering spending the weekend. It is common for the Chateau to sell out most if not all weekends of summer. Right now there is good availability, but that will not last long. Guests wanting to book pre- or post-dates should secure a reservation then call to speak with a reservationist to see what is available; call the Chateau on the Lake 888-333-5253 room reservations 7days a week 8am -8pm; no code is needed only the dates and name of the event. Cancellations and changes must be made 72 hours in advance of check-in date.

The event registration site will be up soon. Please watch your inboxes for an invitation.
