You'll probably be fine, but just follow a couple of basic common sense type rules:
A- Don't be stupid about it and drive into sand that looks dry and soft even before you drive on it.
B- Probably a good idea to have a tow strap with you so if you have to go make a friend, you don't have to hope he has one.
C- If you are driving on the beach with a 2WD vehicle, it is probably best to make sure you are not the only one driving out on the beach that day.
D- If you start to dig in, don't hit the brakes. Keep steady on the gas until your forward momentum slows down, and then get off. Go let some air out the tires and see if you can get moving without digging in.
"The budget should be balanced, the Treasury should be refilled, public debt should be reduced, the arrogance of officialdom should be tempered and controlled, and the assistance to foreign lands should be curtailed lest Rome become bankrupt. People must again learn to work, instead of living on public assistance."
-Marcus Tullius Cicero, 63 BC
