Not that I go to them any more, but to me, the length of travel to get there requires a lengthy rally packed with entertainment. Workshops morning and afternoon, possibly the same ones repeated a few times so any clashing of workshops or other events allowed all to be done with enough juggling around. Bus tours to interesting, places, events or industries within the area, if the rally site is some distance from the main town, a regular bus service.
2 of the better rsllies I attended were Lardner Park in Vic, some where around 1998-99, Canberra 2000, both had great events and entertainment each night, Berri Sa '98 would still be the hilight rally though, by far the best I've attended. The first Tassie rally wasn't too bad, but a lot of back biting and infighting spoilt that rally.
Now as far as a really great get together/rally type thing, Mucking-up would be hard to beat
