At The VERY Least:
Use braided hoses (I don't know of anyone who's had trouble with the braided SS hoses, but anything can happen), and turn the water off when you go out of town.
Turning the water off after each wash is even better, particularly if your washer is in a finished area of the house. A lot of fancy houses nowadays have the laundry area near the bedrooms (where most laundry is generated), and a burst hose could be disastrous there.
Best of all is triple protection. That's braided hoses, a firm policy of turning the water off after each use, and a drain pan (plumbed to a drain line) under the washer. That way, you're protected against hose problems and washer floods. If your washer is in a concrete-floored basement with a floor drain, you can skip the drain pan.
You're talking to someone who turns the house's water off at the shut-off valve when going out of town. No way do I want to come back to a flood, thank you very much!
P.S.: I highly recommend using Teflon tape on the faucet threads when installing new hoses. Even though there are new hose washers included with new hoses, washers can let a little leakage through. Teflon tape stops it, so you don't end up with a little punky spot in the subfloor under your washer's faucets.
