If you do not eat gelatin, you'll want to ask the chef which desserts are made without. When we were there last December, they had changed the source of the baked goods, and most had gelatin in them. For dessert, I could have the fruit, cookies and maybe the ice cream (I can't remember).
I have had better luck with veggie items at PF. Chef Harry walked me through the buffet, to tell me what was veg, and brought me a plate (items not on the buffet) with tabouli, edamame salad, cucumber salad & hummus.
Have a great trip.
