Post your favorite Vegas shortcuts and tips

[dozer]

I'm heading to Vegas in three weeks and was interested in hearing all of your favorite shortcuts, tips, tricks, fun things to do, etc. that I could try out. For instance, I heard about some 'side door' that gets you from Monte Carlo to the Bellagio in like 10 minutes or something like that. Also, any really good "bang-for-buck" restaurants/buffets? Certain poker rooms I should try out (besides Caesar's, Bellagio, MGM, Wynn and Aladdin tourneys)?

Looking forward to all serious and sarcastic responses. I want to post a trip report when I return, so I'll credit those who give tips that I end up using.
