Weekend!

It's my first weekend off in Bahrain, any suggestions in what to do?

All depends on what your hobbies are and what things you like to do.

I can't advise deep sea diving if you hate it. Best to give us more information so we can help you better. Bit late now though as it's already Saturday and I've only just seen your post

Bahrain has a number of things to offer. Cinemas, clubs, sports, shopping, eat out ... the list goes on.
Depends on what you like.

A good starting point for you would be to take a look at the middle pages of the Gulf Daily News. There is a very good listing of activities that you could do in Bahrain.
