You have to call them. Sorry, but this is only a comment website.
I'm 260, we go every other year. They always have a few for us "big boned" people. I find the bigger horses are better trained, and respond better to confident riders. Wouldn't go anywhere but the Ponderosa!
You'd have to call to be certain, but I remember that they have a few extra large horses for extra large people for a small extra fee. Again, I would call to make certain, and in case they have to be reserved or something.
