Hi A.,
You can do a tour of Ethel M's chocolate factory; go to Border's for their storytime; check the local libraries for special children's programs, go to bounce-U, pump-it-up (there is still one open in LV) or child-time for indoor play when it's too cold or rainy to go outside. Although your group is on the young side, you might consider ice-skating out at Lake Las Vegas. I think Anderson dairy does tours, but I have not done that. There is also King Putt, an indoor miniature golf that is fun for kids that age. The springs preserve is also a great place. Our group has been taking the kids there since they've been 2, and they still love it. There is so much to see there. Just a few suggestions. Hope some of them help.
