I just read the page on your site, but does the boat go from POFQ to POR to DTD or POR to POFQ to DTD?
In other words, can I take a boat from POFQ to POR?
You can but it would be a tad ridiculous. It is about a 5 minute walk between the two, or about a 5 minute boatride. However, between waiting for the boat, boarding the boat and diembarking, the 5-minute boat ride would probably take about 10-20 minutes. And, when you get to POR, they WILL make you get off, and wait in line to get back on.
We liked the idea of the boat to DTD....until we tried it, and waited over an hour for it. The boat would show up from POR with room for exactly 4 people from POFQ. So, even though there were only about 12 people waiting when we got there, we had to wait like 4 boats. WE considered getting on the boat and getting off again at POR, but there was also apparantly a big line at POR as well, and again they make everyone get off at the end. From when we left our hotel room at POFQ to when we arrived for dinner @ DTD, was almost 2 hours.

Still makes me mad as you can probably tell. A different evening I wanted to go to DTD for AC, I took the bus. Took 15 minutes by bus.
So, I guess what I'm saying is, if you get to the boat dock, and there is any line at all, and the first boat gets there and you can't get on it, take the bus to DTD, and then take the boat back. (The boat ride itself is quite nice.)
