Flying into Las Vegas 6/30 and have a reservation for Railroad Pass. We enjoy places with character & places we can't find at home and I thought after the flight my husband would enjoy hanging out in the casino. We won't arrive until about 9:30pm and will be leaving early the next morning on the way to Hoover Dam. My concern is the mixed reviews. Is the place clean and appropriate for an 11 year old (casino withstanding, of course). Thanks for your help.
