Party planning: Tyrion will be baffled at being roped into this immediately upon waking up, but he likes a good celebration, so why not. Especially if it gives him a chance to inspect the heraldry and whose symbols hang in which area, because that's always useful information.

Festival: Let's be real, he's mostly here for food and wine. And also the carousel and the light show, because those are fascinating and advanced beyond anything he has any experience with.

Planting: Physical labour isn't really Tyrion's strong suit, and he knows very little about the practical aspects of farming, but he excels at organization, and can help keep track of what's been done and what needs to be done and who's where.
