Total waste of time. We went on a Monday afternoon, and we walked around for 20 minutes trying to give Adventuredome an outrageous $16 ($8 per person) for a 1 minute roller coaster ride, but every ticket kiosk was closed. The few that were manned pointed us to other kiosks on the other side of the park, which all turned out to be closed (one was closed for "counting inventory"). The automated ticket machines they pointed us to, which looked like they were built in 1980, didn't even turn on. Eventually we gave up and spent another 15 minutes trying to find the exit so that we could return to the dumpiest casino we went to in Vegas.
