I'm not sure..I know hotels here in Bham were at capacity. I did hear about a gas station in N.O. that was charging $10/gallon for gas.
You should be able to go to some church or school hall for safety.
You don't need to be home if things get dangerous still.
You also need not spend money.
I'm sure the government and local cities have places to go with cots, beds, meals and comfort.
