If there shouldn't be any problems in doing so, Parum recommends that the group tries to get close to the entrance without going through the camp. Since the entrance is a cave, there should be a mountain or cliff it's attached to, so the party should move around the camp, onto the mountains, and try to get above the entrance.

I'm hoping they could get somewhere around 60 feet or so before they try and attack. Additionally, Parum would try to make sure the group won't be easily seen by someone who might be watching the entrance itself, hence the silent image. I suppose one way she could save on spell slots is if someone can tether a 50 foot rope near the drop off point, and then after dealing with the guards we could just rappel down the rope and drop the rest of the 10 feet. I know we have rope, whether or not we'll have anything to secure the rope to will be a problem.
