Does anyone know how frequent the boats run between POR and DTD? We stayed with the in-laws at Saratoga Springs during our last trip. We waited what seemed like an eternity for the boat to take us back to the resort. Of course, my memory could be skewed because I was holding a heavier-by-the-minute toddler who was teetering on a major meltdown. I'm hoping we don't run into the same thing this time around! Thanks for any input!
