I enjoyed the murder mystery event in the Golden Saucer, but then I started thinking how nice it could be to have a separate storyline from the main game developing in the Golden Saucer. Then I thought, what about Golden Saucer dailies in the spirit of the beast tribes? I actually really like that model.

Do various Golden Saucer quests like help Roland deal with rowdy guests, help the golden saucer crews with maintaining the attractions so they stay in top shape. Participate in an experimental new attraction to help them work out all the issues with the ride so that they can eventually release it to the public.

After gaining enough reputation (or some other measure of progress) you would be able to unlock the next part of the storyline for the Golden Saucer. This would add more character to the place itself, and offer another opportunity for gaining MGP.
