Depending how rushed you are. I had a few days in Oahu and rarely had to queue at any of the stores. At most about 20 minutes at Gumps or 10 at Ala, but I left the queue, shopped elsewhere, came back later and usually could get in with minimal wait.Thank you.
Also, is it best to make an appointment to visit the stores? I’m hoping I don’t have to wait in line.
If you're time pressed I'd always suggest booking an appointment though, especially if you're visiting around the time of a new launch.
