I spent some time in the casino prime time lots of people. Since the bar is no longer there an extremely long wait time to get drinks. Comedy show full crowds +18 shows. Line was all the way back to the casino on one show. I actually waited at the door for the end of the line to go inside and I was still able to get two seats with table almost in the front. So the lounge holds more people that I thought.
I cruise recent from Seattle and use port valet. It was great, Hope you can use it. To answer you question. When walking around Pike Place we saw this store "The Purple Store" and they had a sign that they check your luggage.
