Weight Limit, opps

So, we are quite interested in the carnival excursion of the scenic railway and the helicopter tour. I noticed when you click in to book the excursion it says "Guests weighing 250+ pounds will be charged a surcharge". Well, um, since the cat is out of the bag as I am asking in the first place, lol, does anyone know how much this "surcharge" is? I'm also wondering if there is only a single priced surcharge, or if there is a difference if someone is 10 lbs over compared to 50 or 60 lbs over?

I can probably just call and see but figured I would check here first if any other "heavyweights" have done this excursion :D

Besides, sometimes it can be difficult to get the phone lines to answer simple questions so I can only imagine what kind of answers I will get on this if I called in :rolleyes:

Thanks!
