Call but I am sure all Disney resort guest can use activities at other resorts, except pools. I know we last year went over to fort wilderness for several activities, since it was a huge place and we had several places to go through out the day we rented bikes, no problem, we asked for checkers and had no problem getting them, we sat at the movie and had no problem, asked for a fishing pole (was that FW or WL I forget), had no problem. We paid for and had no problem with archery and horse back riding. I know we did even more and never had a problem, just scan our ban and got what we needed, if there was a fee we paid the fee. There is a recreational phone number, where you book boats, horseback riding and cabanas, I think if you look on my Disney and found that number, I bet they could answer your question. Also if you are at POR you have a huge option SS, OKW, FW are all somewhat close, if you don't drive, you can take the boat down to DS and then take OKW or SS.
