Pike Place Market is not able to offer any lockers or storage. If you are a cruise-line passenger or a guest in a local hotel, we suggest checking with concierge services on the ship or at your hotel. The Port of Seattle offers complimentary luggage transfer to the airport at the end of your cruise. Click here for more information.
Alternatively, you can use a third-party resource for temporary storage. UseBounce has a few locations within a couple of blocks of Pike Place Market.
