Here is what my experience has taught me:

First, don't worry one bit about slowing the game down by raising odd amounts. Most dealers are very quick at making change. If you open for $12, it won't faze a soul.

Second, I have seen the absolute most common raise to be 5xBB and most people don't adjust for added limpers.

Third, people are MUCH looser about calling raises in a casino. If you make a big raise with a big hand you will probably get called by the same donks who would have called a 5xBB raise.

Fourth, you should tend to value bet more often in a casino game and give less credence to small raises. I see people calling value bets and even making small raises 'to find out where they are' with some pretty weak hands in casino games. Punish these people!

Fifth, you should be more careful about trying to buy the pot preflop. Personally, I make plays at the pot preflop about 50x as often online as in a live game, simply due to the fact that it almost never works in a casino. In fact, if you simply removed the 'preflop steal' play from your arsenal in a casino game, you probably aren't giving up much. Simply put, assume your preflop raises will get called, probably by 2 or more people unless the raise is huge, and even then it could get called by many people.

Most importantly, do not just raise a 'standard raise' or anything like that. As some have already pointed out, make the raise that will produce the size pot that you would like to play. If you have not already done so, read Sklansky and Miller's chapter in No Limit Hold'em on sizing your preflop raises. I cannot stress how much more important this concept is in a casino game, mostly due to the fact that no one is trying to figure out what your different sized raises mean and the fact that most preflop raises are called and you will have to play postflop.
