when you say lads what age are we dealing with. it is common for a group of golfers aged 60 -70 to describe themselves as having a lads week away!
I suspect you may find Los Boliches a little sedate in the evening and would be better going to Fuengirola. In your situation one walk in will be enough to convince you to look at public transport and I would get the train at los Boliches station . It is only one stop but worth it.
When you get to Fuengirola you can head for the sea. When you get to the paseo turn left and you are in a very lively younger area which is more than the London Pub.
Before you have got as far a the paseo you will pass C/Capitan which has a number of bars de copas but not until quite late, 11 is early. they should be enough but there are a few others scatted in the area around Church Square.
