As you drive, air will flow over the radiator, which helps the coolant get cool again.
Why does my car overheat after 30 minutes?
Two things should happen; first, as you suggested, the hose should feel "hard" and you should always feel motion through the hose. One other thing to check is your heater. If the heater is not working (supplying hot air), then you've got an obstruction inside the heater core; which can also create overheating problems.
Why is my car overheating when idling?

Should the coolant reservoir always be full?
Your coolant reservoir tank should be at least 30% full. Most reservoir tank has a min and max mark drawn on the side of the container. What is this? The most common cause of a coolant leak is a bad radiator cap, bad radiator fans, and loose radiator hose clamps.
How do you fix a small coolant leak?
If a radiator hose has a small leak, something like Flex Seal can be used to patch it for long enough to purchase a new hose and do the job right. If your radiator evacuates its fluids and the surrounding air is below 30 degrees Fahrenheit, you can drive for a short distance without damaging the engine.
