The lodging for Congress participants at the Sentrim 680 Hotel is made through the conference secretariat, by registering for a conference package. Registrants may select a 3-day, 4-day, or 5-day package. The three-day package is for Thursday, Friday, and Saturday nights; the four-day package can be either Wednesday night through Saturday night or Thursday night through Sunday night, and the five-day package is Wednesday night through Sunday night. The "off-site" option means that you do not intend to stay in the housing provided by WANGO. In this case, you must arrange all of your own accommodations for the duration of the Congress.
