I used to live in Gibralter many years ago, and when we returned and visited the Rock when we were on a cruise a few years ago, I couldnt believe how the place had changed, for the worst unfortunately.
Apart from visiting the apes at the top of the Rock, and a few reasonable places to eat, it is, as Gill says, nothing more than a Duty Free Zone, with people by the score walking up the main street, carrying all their goods and then returning back to the cruise ships.
