Bumberdetails: How to navigate Seattle's music and arts festival

Hours: 11 a.m.-11 p.m. Saturday-Monday, Seattle Center.

Tickets: $50 per day; some multiple-day passes still available ($120-$420); free for children 5 and under; $15 at the gate for seniors, people with disabilities and kids 6-10 accompanied by a paying adult (www.bumbershoot.org).

Mainstage passes: A ticket gets you onto Seattle Center grounds. An additional free pass is needed for evening Mainstage shows (on Saturday, Old 97's and Sheryl Crow; on Sunday, Michael Franti & Spearhead, and Jason Mraz; on Monday, Franz Ferdinand and Modest Mouse). They are given out on a first-come, first-served basis at three outdoor-ticket booths: (1) on the road between Bagley Wright and Intiman theaters; (2) at the south end of the Fun Forest Pavilion; and (3) on the east side of the Center House.

Getting there: Parking in Lower Queen Anne during Bumbershoot is limited and costly. (Find a list of Seattle Center lots here: www.seattlecenter.com/transportation/parking.asp.) Public transportation is strongly encouraged. Use Metro's Trip Planner(tripplanner.metrokc.gov) or call 206-553-3000 to plot your strategy. Bike parking is available at Fifth Avenue and Thomas Street between the Space Needle and Experience Music Project/Science Fiction Museum.

What to bring: Cash, if you're going to need it for parking or food (many vendors are on site); keep it secured. Food and nonalcoholic beverages are allowed through the gates; beer and wine must be purchased inside the Bumbershoot beer gardens with proper ID. Reusable water bottles are recommended. Also handy: a sweat shirt (for evening, when it can get cool) and extra clothes for kids who might play in the International Fountain.

What not to bring: Bumbershoot has a big list of no-nos, including weapons, alcohol, audio/video recording equipment, cameras with detachable lenses, glass bottles, wagons, jumbo coolers and backpacks larger than 17 by 12 by 10 inches. See the list here: www.bumbershoot.org/info/policies.htm. Bags are subject to search at the gate.

Accessibility: One Reel makes every effort to accommodate everyone, providing special parking, interpreted concerts and a limited number of courtesy wheelchairs. Find the Bumbershoot Access Guide for Persons with Disabilities here: www.bumbershoot.org/accessibility.htm
