Me, my brother and my dad are taking a one-week scuba vacation in June.
Since I want to make up for lost time with my dad, I'm bringing the Castles & Crusades Players Handbook, the Monsters & Treasure book, the screen (if I can rustle up the cash for it in the meantime) and some dice.
I've had my dad make a more advanced character than the simple Beyond the Wall characters. He's picked a rogue with a half-class of bard. (He really wanted to be full bard but I broke the news to him that it would more or less restrict him to social and intrigue games only.)
I'm not sure what my brother will play. (He played a meatshield last summer.) Probably something multi-classed, since I want to make sure healing and melee are covered. (He'd make an interesting paladin.)
I'm thinking of having an Indiana Jones-style adventure, where my dad's character finds out that his lifelong rival -- who signed up hours earlier than he did at the Delvers Guild in Ptolus, wooed the girl he had a crush on, etc. -- has bought another copy of the treasure map he and my brother's character just spent all their cash on.
So they'll be arriving after the rival has gone into a trapped complex within the Dungeon (since I want to give him some stuff to use his rogue skills on). Unbeknownst to anyone, though, the guy who sold both copies of the map is actually planning to ambush the survivor -- shades of the Raiders of the Lost Ark opening -- once these two competing groups have cleared the hazards and recovered the treasure.
I'm planning on drinking up a lot of Indiana Jones inspiration and coming up with a complex of about 10 rooms at most for them to explore.
