I guess a good tactic with this would be --

After we destroy the evidence in one room -- as allowed per the rules -- we could set up a portal to that room from one of the next rooms we visit. Or perhaps if we know that one room has really good evidence, and another has none or little, we could set up a portal from the good to the bad.

I don't know if all the moves from all teams will be made public after they're made, which might change the strategy a bit.
