Both of the PO resorts and OKW and SSR have the boats pictured above to DTD. The PO's share boats and the OKW boat stops at SSR coming and going to DTD...nice rides from all locations!
DTD boats from POFQ/POR are lovely, just beware of the "Mosquito" months and be sure the bring repellent, I was bitten the worst during evening trips.
Also, smaller children may be spooked by the darkness in the evening, my DD insisted we take the bus back after dark, although she didn't much enjoy the trip when it was still daylight, she toughed it out
