I think some of the hotels have daycare/babysitting facilities, but personally I'd rather not leave my little ones in the company of strangers in a strange city. Maybe when they're a little older, but not as babies/toddlers.
I have no idea what we're going to do with our little ones. I don't want to bring them with, they would be way too much work and I wouldn't get to socialize & get OUT at all. I'd be stuck taking care of them all day, same as I am here. Why go to LAS, pay for a hotel, to do the same thing I do here day in day out. I'm hoping I can convince my mom that they're really not all
that much work to take care of....... (yeah, right, they're more work than one can possibly imagine) and maybe she'll come to our house and watch them. It's not that I don't love my kids, but it really would be a lot of work & hassle to have them in Vegas, and they're too young to get anything out of it. If they were older and could take in a show, or see the Star Trek exhibit, or take anything away from the experience, I'd do it, but they're just babies.
So I'll just have to hope that the baby gets over his colic & nightly screaming sessions, and that the toddler gets over his tantrums so Grandma will stay with them for a few days!
It is a few months away, so I hold out hope that at least the colic will have passed by then.
