Hey, it`s a small world :-)So what club are you trying to promote,can`t think of anything in immediate vicinity of Holyrood Park?
The Crags project was nowt to do with me, it was part of the Lux Europa project. Various outdoor lighting projects across Edinburgh, there was a tourist slide show on to the castle rock as well as others. Some worked better than others thats for sure, some of the sponsors refused to pay up when they saw the results.....
The Grags was originally going to be a clock but they had some difficulty getting something that could take the heat in the gate of a Gladiator. It ended up as a rotating oblong and triangle projected from pair of Gladiators on a scaff tower about where the play park is at Dumbiedykes.A very, very expensive pair of rotating shapes.

Commercial advertising in the Park will be no go at all, I`ve been pulled over by the Park constabularly for driving a lettered vehicle in the Park.As it`s a Royal Park Historic Scotland look after it on behalf of the Queen.
Additionally with something that may shine into the sky you need to inform the Civil Aviation Authority,CAA, as it may present a nuisance to aircraft.
Aurthurs seat is about 850` tall above sea level, close projection points are few and far between though, so that is why in the Crags example Gladiators had to be used.It gets into using multi kilowatt xenon sources where a spare lamp that will last mebbe 250 hours is £2,500 plus the unit it plugs into.Hire charges are big.
So would honestly rule out Aurthur`s Seat as a possible , and its a nature reserve.
Another example of how big projection eats up power and cash is the Three Sisters Pub in Cowgatw, they have had various go`s with moving lites projecting on the wall above the beer garden, none have been entirely satisfactory, with projection there is no such thing as too much power.
What seem popular at the moment are Space Flower type searchlight effects:

Rental costs are still high but a proven attention getter, don`t forget to plant the standard UFO sightings in the local papers ;-)
Or projection onto buldings around Edinburgh, need a van or pickup with a generator onboard and a bright moving light, x-spot mac2000 or similar for ease of lining up when you park, or possibly just a 2k profile spot and jump out and focus manually or from rear doors of vehicle and a good camera to get those important publicity shots.Getting hassled by the cops is part of the fun and remember to tell the papers....
This one is possibly best one with a level of affordability, look around for buildings with big flat surfaces and somewhere to park in range and square on for a bit.
Could be a fun project, if you need more help my email is in my profile.
