Thank you so much for the comment, Pliskin!
Scoring is 1VP per player with pieces at hotels (guests) and 1VP per set of three hotels in a stack for a max of 6 VP in a four player game. Don't think I've ever gotten that much, but the "completed hotel" is if the other players decide to boycott. For crafting, you spend matching stomach cards to activate hotels, and craft a card still in your hand. Scoring at the start is so that hotel tiers have to stay on the board to score but players who took advantage of the hotel effects are counted even if you battle them.
