About Parking during the Conference!
As was the case last year, Associated Grocers is hosting its two-day event during our conference dates. That means that we could be competing for event parking in the garage attached to the Radisson. This is especially true for those who arrive late (after 8:00 a.m)  The link below provides information about other nearby city-owned/public parking options. Click on the larger "P" symbols for the address, rates and hours of a given city garage.  The green lines shown on streets indicates the availability of two-hour, on-street parking which may not be suitable for our attendees.  The purple lines indicate areas where ten-hour, on-street parking is available. As a reminder, GSDI is no longer paying for attendee parking.
