My original working life meant going to lots of places, often only once - and I was forever getting lost. Long before satnav too. I used to dread the phrase "you can't miss it" - I'd always miss it!
When we first discovered Calis/Fethiye I was surprised how quickly I learned my way around. You'll be surprised too. If you think of it as just half a dozen main roads, everything is pretty much 90 degrees off one of those. Learn the 6 roads, that's you sorted
