Is their a strategy that works best for learning tunes, (jigs, hornpipes, polkas)?

I can get some tunes from the dots but getting to the point of playing at the club from memory can be a bit of a jouney.

What do people find?
1. Just keep playing it, 20 times 50 times 100 times.........
2. 5 times 10 mins off, 5 times, 10 mins off .........
3. 10 times today, 10 times tomorrow .............

I would be interested to know.
