I have been reading on another board about converting park hopper passes over to annual passes. Would this benefit me if I am planning on a second trip to wdw again in Aug. after just being there in March? I bought the ph passes in a package through a travel agent. Would I be allowed to switch the passes if I have not yet used them? Will this save me money in the long run? Does anyone know where I can go to find out the difference in prices for these? Thanks!
