We were there in March, the DinP excursion went the the shack location and as you say it is dismantled during the tourist season, however the location is still worth visiting and is recognisable from the programme. From there we visited the harbour, onto Catherine's bar where we had a drink sat at the very table where the last scene of Beyond Paradise was filmed. Then into the police station which is just as you see in the programme, even the cells, no imagination needed. An excellent trip.
