Why Stay in the ESA Housing Block?

More Networking!

You will be in the center of conference activity. You will be able to network easily with other conference attendees and interact with your colleagues when not at the convention center.

Express Entry!

To provide for a crowd-free check-in process, ESA will be providing Express Entry.  Express Entry will provide for registrants to pick up their badges and conference materials at the three (3) host hotels. Only those registrants staying within official host hotels will get this benefit. Once you get to the Conference Center, you do not have anything left to do but enjoy the conference.

Best Hotels, Great Location, Lowest Rates!

The conference staff have taken their role of finding a conference site very seriously. Based on a guaranteed percentage of attendees staying in official conference hotels, ESA is able to negotiate with the hotels to provide discounted rates from their normal rates which saves you time and money!

Support the industry and ESA!

Support the conference and the association by staying at the official conference hotels.  Unfilled rooms can cost the association thousands of dollars which can apply pressure to increase the conference registration fees to offset these costs.
