We just got got back from Adventure of the Seas. Wonderful ship and itinerary! I used a small tote bag for pool/land use and kept my sea pass in there. Around the ship and at dinner I had a small flat tapestry bag with a long cord that I wore across my chest. A little warning, though: my husband, son and I all had to have our sea passes replaced when they stopped working in our staterooms due to having had them too close to a cell phone, walkie talkie or the magnetic clasp on my evening bag which I bought on board! They replace it no problem, it's just something to try to avoid.
