I have some unexpected time off and am thinking of going to Las Vegas later this month. It's been forever since I've been to Vegas, probably 20+ years.

Can anybody offer tips, tricks, suggestions for a week long stay in Las Vegas?

Should I try to work out my own best deals going from hotel site to site, use an online Hotel finder or use a travel agent?

What about a car? Has Vegas developed enough between the strip and downtown to be able to get around without messing with a rental car? It would be leisurely and I would have no schedule, times to be anywhere, etc.

I know air fares are pretty low right now, I can go Southwest for $220 round trip. I'm mostly wondering about the car thing and hotel suggestions, whatever.

I'm all ears as to anything you have to offer. Thanks in advance!
