A steep walk up with great views, an alternative route available for less strong walkers Is available we think.
Very expensive attraction, a little cheaper on line in advance. Staff at entry seemed confused about electronic entry ticket, odd. Signage not too good but assisted by staff who recommended going with a guide but didn't explain this well. Told it was 50 mins. Waited for a short while and joined a dozen people. The talk began in a crowed room with people pushing past all the time. It was very detailed and technical and people slipped away gradually. Though well presented and interesting spending nearly 1 and a half hours, in one hot darkened room looking at four items was not in the end a good experience. We came out shell shocked with little energy left to see the rest. This needs re consideration and much better advance information.it is for enthusiasts on Harrison and navigation.
Spent the little remaining time we had skimming the rest, some of which looked interesting but didn't have the energy to use the complicated audio guides. Again poor directions and a not informative map. Meridian line is a tourist photo trap, the education centre was poorly organised with useless instructions and things that were broken. The planetarium shows were charged in addition.
Left tired and annoyed, spoiled by poor communication on many levels. Note many many many tourists, some being very childish and ill mannered much of the time which didn't help.
