Estimated length of Play for Master of the Fallen Fortress?

[Peter Kies]

I'm organizing an event and it was suggested that I include at least one module. I picked Master of the Fallen Fortress, but I'm not sure how much time we'll really need for it in the schedule. The default suggestion for modules is that they are equivalent to 2-3 scenarios in length, but this is a Free RPG Day 16-page module, which are listed as "more like a scenario" in length. I have no more than 5 hours per slot (that includes break/transit/setup/marshalling) and this one looks like it has a lot of encounters. For those who have run it or played it before, how long did it take?

I ran it as a one shot for my group using PFS pregens and we wrapped in under 4 hours.

I ran this recently, on a PFS Games Day, with a large group of level 1s and 2s. Even with some scaling up of the encounters, it finished in just over 3.5 hours.

There is only one roleplaying encounter, the rest are combats. All of the combats are fairly quick.
