Flew in there many times on a 767 - hope that your first time its CAVOK 'cos the approach can give one quite a shock. I strongly suggest you do some homework before going in. Getting out - just keep in mind 4dme - stay in that cirlce and you are ok - go north a mile or two and we will read about right here on this website.
Layover - beers are cold - get out and see the local area - enjoy.
