I am there at least once a year, and only ever went to the visitor centre once, anyone with Scottish blood in their veins has to go there, you will know why once you are there, as one of the other posters said, there is a haunting 'feeling' on the field that can't be explained to the casual visitor, many of us go there and simply cry, last year I was fine, then a total stranger came up to me and asked me who I was (Clan wise) I answered, and then the two of us just stood looking at each other crying openly.
Without another word, we shook hands and went our seperate ways - thats the magic of Drumossie Moor to the Scottish psyche....Trust me, you will never regret going, visitors centre or not...
