Time to Run 'Sundown on Starmist'?

I've got a gaming day with 10-12 hours to run some Star Frontiers game.<div><br /></div><div>I've not run any of the Star Frontiers modules before. These will be adult players who will fairly focused on the game.</div><div><br /></div><div>How long on average do you think it would take to run the 'Sundown on Starmist' module? I know it will vary greatly, but just want to know if this is something that you would expect to finish in 12 hours or less. I would presume it would take longer than 6 hours?</div><div><br /></div><div>Thanks in advance!</div><div><br /></div><div>-- Stan</div>
