I don't know if POR has water mice, but they do have canopy and pontoon boats for rent. I do know CSR has water mice as well as the deluxe resorts and you can also rent them at DtD. IMHO the best place to rent them is from one of the monorail resorts(GF, POLY, CR)or WL. This is such a large lake and the water mice are faster there. Our 2nd favorite place to rent them would be YC/BC/BW area at the YC marina.
