I'm looking for a clean, smoke-free room to crash in while we cope with massive jet-lag. Affordable and preferably on the strip. I don't really care about the other amenities.

It's been a long, long time since I've been to Vegas and although I've never been disappointed with the rooms, after searching reviews online, I'm now scared! It seems like a few places haven't been updated at all. We'll be traveling with a 4-yr old, so my #1 concern is cleanliness and the room quality. I'm guessing we'll be in the room for good majority of the time because of the huge (9 hr) time difference. I figured that being on the strip would be a good thing for a little late night wandering.

If anyone's been to Vegas within the last year or two. Please recommend a hotel. Thank you!
