It's been about 7 years since we've been to Vegas. We had our kids this time (ages 17 and 14). As some others have mentioned I would leave the kids out of this one. It is still a fun sight to see if you've never been there, but in case most don't know marijuana has been legalized for personal use and the casinos are the only ones that don't allow it. We walked thru a constant smell of weed and I was hit up twice by homeless people asking for money.
I was used to seeing the girls partially dressed and posing for pics etc. That is part of Vegas and I expect some panhandling, but I wouldn't do freemont again unless it was a party trip.
If you do go down do the zip lining and eat at the Charter House inside the Golden Nugget. Food was outstanding.
