If everyone is going to the Blue Recluse to hang out for food and booze, then you can be sure the Ghouls know this and will be there shortly after you show up - just in time to ruin your dinner - and make you theirs. Be creative, hide places no one else is - think about what other people would do and then don't do it. What is the logic place to go? or the logic thing to do? Do the opposite. This is not the time to be a lemming or a sheep.
Well duh! Arm yourself - whether its firebolts, nature's wrath og a heavy claymore. Try not to rely on only one type of arms. If your sword breaks, or you drop it by accident you need a backup. If a large abomination proves impervious to fire then make sure you got an alternative ready. Adapt and overcome as a certain group of Alliance soldiers say.
#1 Pick a good location to hide!
This is somewhat connected to #3 but it demands further attention. A good location is not only defensible by a minimum of people, but also allows for multiple exits, don't let pesky ghouls or cultist lay siege to your pillow fort, make sure you have at least one - preferably two - alternative ways out. Be a fox, pick a good foxhole. If you don't have the manpower to properly defend the place, then make sure to minimize the attention you attract, only light fires in daylight where they are harder to see, unless you can shield the light, then do it at night so the smoke is harder to see against the evening air. Don't dance and sing and yell, keep the noise down. That includes couples yelling about who is doing the dishes and telling your mom's new husband that he is not your real father. Shut up and keep your head down.
