If the idea is 'to have a sniff'; most schools with a tailwheel machine will do and so will the 5 hours.
The machines usually operated by these schools tend to be benign and the average pilot will manage to learn to pull off a decent 3 pointer in benign conditions in those 5 hours.
However if you want to become truly proficient in the art of mastering the tailwheel machinery in more challenging conditions and circumstances, make sure you go to a school with good instructors who are true tailwheel afficionados.
They are usually quite easy to spot by asking if they are happy to teach you wheelers as well as three pointers.
Whatever you do have fun!
