We have stayed at the Stratosphere, The Mirage, and the Marriott (Marriott was off-strip) with kids.
We used to go meet DH's family there every year.
Vegas is not our favorite place and we would never choose to go there on our own. We have only gone to meet family who liked it OR we have gone for business trips.
My kids did like going up in the Stratosphere (we weren't brave enough for any rides but we did eat up there in the revolving restaurant. We also did Circus Circus but I think that is gone. Kids went golfing several days, went to the Hoover Dam, and walked around to see the themes of several hotels. They also liked the light show. We had tickets to Seigfried and Roy but that was when they had just had that Tiger attack so we weren't able to go.
My middle son was sick and we were trying to get him to the nearest bathroom ASAP, but the security at the hotel (can't remember which one) in the casino made a HUGE deal about him not being old enough to leave the solid red portion of the carpet. In all the fiasco we didn't make it to the bathroom on time so my son promptly threw up on the solid red portion of the carpet!
I had to laugh because A.) if the guy hadn't made us stop, we would have made it to a toilet, and B.) because even though the guy seemed annoyed, I was quite sure they had seen many a vomit on their PATTERNED portions of their carpet!
Did I mention Vegas is not our favorite place?????
