For a family or group, renting a houseboat can make a fun vacation. Call well in advance to book for summer months.
In addition to renting the boat, be prepared to pay for fuel.
Don't motor at night.
Check the tide tables before docking for the night and before passing under bridges.
Check currents and wind conditions before docking.
Bring linens and sleeping bags.
Pack light, since storage space can be tight. Bring sunscreen, bug repellent, a flashlight, warm clothing for cool nights, and extra towels for bathing.
Bring groceries with you, since a marina's selection can be limited.
